The hit series known around the world comes to US television. At an exclusive boarding school in England a girl named Joy goes missing. And taking her place is American named Nina. Patricia, who now has to share a room with Nina thinks Nina has something to do with it. But, there are more secrets to be uncovered in House of Anubis.
The students return after the holidays, but who is Jerome avoiding and why? Amber is regretting agreeing to be Alfie's girlfriend. Sibuna has a midnight feast in the attic and are soon joined by the rest of the residents in Anubis house. Amber finds a dollhouse that is an exact replica of Anubis house. They get caught by Victor and everyone files down the stairs and back into their bedrooms, but Nina is determined to look for a new hiding place for the Cup of Ankh. Victor finds her as soon as she puts it into the secret door. He startles Nina, causing her to knock a box off the table. As Nina goes downstairs, she hears Victor pick up the old doll that she knocked over. It recites a riddle about a book of old, water of life, and tears of gold. She tells Fabian all about it and they agree to check out an abandoned library for the book of old that the riddle mentioned. When they do so later that day, they find Mr. Sweet and Victor already in there. They hide behind a bookshelf and hear them talking about the Book of Isis and where it might be hidden. Fabian knocks something off the shelf and the episode ends with Victor pulling the sheet off it, leaving him to find them.
Nina's grandmother comes to visit the house. A seventh grader blackmails Jerome. Alfie tries get Amber to be his girlfriend by giving her raspberry cupcakes, but Amber is allergic to raspberry and develops a blotchy face. Meanwhile, Nina has a dream inspired by Victor's riddle, which she has overheard. A malignant spirit emerges from the cup. Sibuna finds out who is blackmailing Jerome, and Victor is convinced that he will find the Book of Isis in a traveling Egyptian artifacts exhibition. Nina hears some noises and goes up to the attic to examine. She takes the cup out of the hiding place, and Senkhara comes out. The spirit tells Nina to find the Mask of Anubis before anyone else or forfeit her life. Trudy cleans out the attic to prepare a guest room and throws out the dollhouse. Alfie saves it to give to Amber and passes Step 1 in Amber's dating book.
Mara is upset that Mick's family is moving. Alfie tries to impress Amber with one of his photos in a magazine cover and passes Step 2 in Amber's dating book. Fabian writes a poem for Nina, but Nina has something else on her mind. It is discovered that someone else might have found the path to the Mask of Anubis. There is a replica of the Mask of Anubis in the exhibition, so Nina and Fabian go check it out. Jerome's sister, Poppy, reads her father's letter to Jerome. Meanwhile, Fabian's attempt to read Nina his poem fails, and Nina has another terrifying dream.
Senkhara leaves her mark on Nina, and Fabian's godfather, Jasper, advises her about the mark and the Mask, which he believes to be a myth. Jerome finds Fabian's poem to Nina. The dollhouse begins to communicate with Nina, and Nina thinks that the Mask is in the house. Nina starts to become jealous of Fabian and Joy spending time with each other. Alfie passes Step 3 in Amber's dating book, and Amber tells him that they need to have a trial date before they are officially "together". Mara decides that she needs to make Mick break up with her so that he can go to a sports school in Australia. Mara takes Patricia's implicit advice and acts nerdy around him. The plan fails, making Mick like Mara even more than before. Later on, the dollhouse opens a hidden compartment to reveal a map. Poppy researches her father and discovers some interesting information. That night, Senkhara marks Fabian as well.
Fabian decides to keep the mark secret from Nina. The map leads Nina to think that the mask is hidden in the house. As Fabian and Alfie set up a picnic for their double-date with Nina and Amber, respectively, Alfie keeps saying that he wants to give Amber the best so that she does not "put him on the bench". When Nina and Fabian are in the cellar, Nina tries to discuss with Fabian how Amber keeps saying they were best friends before and still are, instead of being boyfriend and girlfriend. Fabian thinks Nina is trying to say that they should break up. The two mutually decide to break up. Amber saves Nina and Fabian from Victor when they are caught in the cellar. Mara finds tickets to Australia in Mick's locker and believes that Mick will break up with her and leave. She finds out later that Mick's dad had sent him the tickets as part of the bribe. To make his decision easy for him, Mara breaks up with him. Joy reads Fabian's poem since Jerome put it on her clipboard after finding it, and she believes that it is for her. As Joy hugs Fabian after what she thought was help in the opening speech, Nina sees the jackal mark on Fabian's arm. Because Fabian said that he did not have any mark to Nina earlier, she becomes mad at him. Amber agrees to be Alfie's girlfriend without posing any more tests. Meanwhile, Poppy sets out to look for her father when Jerome does not want to be involved in the investigation.
Sibuna finds an antechamber and several amulets. Mara is still upset about Mick while Jerome creates trouble between Mara and Mick. Mick prepares to leave for good. Everyone throws Mick a surprise party, but Mara decides not to go. Jerome decides to hire a private investigator to find his father. Mara finally decides to say goodbye to Mick. Nina, Fabian, and Amber go back to the antechamber to investigate further. Amber pulls a book and finds a tunnel behind the antechamber bookshelf by doing so.
Amber is temporarily blinded by a strange beacon that is apparently a trap. Nina and Fabian discover the only thing that can protect them from the beacon: the amulets. Nina and Fabian explore the first task, set by Sarah's father, Robert Frobisher-Smythe, in the tunnels. The answer lies in some old tomes, but one is missing. Jerome reads a letter to his mum from his father and makes a shocking discovery. Anubis House is assigned a new housemother, named Vera, and she appears to be more suspicious than anyone.
A new boy, Eddie, arrives and instantly makes an enemy in Patricia. Amber surprises Nina by finding something that Nina has been looking for. While Jerome plans to scam some money out of his classmates, Vera, the new house mother, and Jasper have a secret meeting. Eddie causes trouble at Jerome's fundraiser, and things become worse when Mara figures out that the entire fundraiser is a scam. That night, Senkhara invades Amber's dreams and attempts to mark her as well.
Nina and Fabian puzzle over the mysterious cube that they have found in the tunnels, but it falls into the wrong hands. Soon, Jasper steals it for the Collector, his apparent patron. Nina figures out how to make the mysterious cube into a key to unlock the first door in the tunnels, and, soon, Sibuna faces their next task. A deadly endeavor that involves potentially fatal traps.
Sibuna's next task is a deadly Egyptian version of hopscotch. If the sequence is not correct on the first try, the ceiling descends to crush everything in its path and keep the mask hidden from the world until the end of time. Meanwhile, Jerome is desperate to clear his debt after his charity scam fails. He starts selling masks and dresses for the dance. Unfortunately, he, setting himself up to be ostracized, sells Nina, Joy, and Mrs. Andrews the same dress. Sibuna figures out the correct sequence to safely cross the deadly hopscotch. In a dream at the end, during the dance, Fabian and Nina share a kiss. Then, when Nina hears Senkhara calling, she follows, but she can be walking into a trap. The episode ends with the dream.
This is the day of the ball. Amber, Nina, and Fabian had the same dream involving Senkhara pushing Nina into the chasm the night before. Vera and Trudy have a bake-off during the ball. Mrs. Andrews finds a receipt near Vera's cake and suspects she may have bought it. Also, down in the tunnels, Amber, Nina and Fabian attempt the deadly hopscotch challenge on the night of the ball. The three complete the hopscotch challenge, but there is a bigger test to come. Eddie gets Patricia into trouble over the music and then saves the day. Nina and Fabian are alarmed to see that their dream from the night before is coming true.
The Collector intimidates Jasper into giving him the key to the exhibit, but Trudy finds out and becomes suspicious. The Collector creeps into the library to examine the Exhibition, leading to a close shave for both Nina and Victor. Jerome and Alfie bet Eddie that he cannot convince Patricia to dance, and Eddie wins. Nina figures out how to cross the chasm, but when she runs to tell Fabian, she sees Joy kissing him. Upset, she flees to the tunnels while Jerome reads the letter that his father has sent to him and his sister from prison. Nina is angry with Fabian, but she shows him and Amber the crocodile beam, which they need to use to bridge the chasm. However, the quest becomes even more dangerous because Victor is now closer than ever to discovering the tunnels.
Jerome finds out that his dad wants him to visit in prison. Patricia softens her attitude towards Eddie and then finds out about his bet. Joy and Mara sign up for the school website. Amber and Fabian enlist Patricia and Alfie to help them fit the bridge across the chasm, but it almost falls in. Sibuna practices laying the beam, and Victor finds the lock in the cellar. Alfie fails to dump Amber while Patricia plans her revenge on Eddie. Jerome and Mara visit his father while Sibuna encounters a new danger at the chasm.
Victor and Vera hide in the cellar and see Nina exiting. Thus, the antechamber code is revealed. While Sibuna practices dodging pendulums, Patricia's revenge on Eddie backfires. As Sibuna enters the antechamber, they are shocked to find Victor standing there. Victor has been blinded by the beacon flash, though, and Sibuna only just manages to avoid him. Poppy finds out that her father wants to arrange a prison visit and that Jerome did not tell her. Sibuna crosses the chasm but then finds a dead end. Senkhara becomes angry at Nina and gives the mark to Amber, Patricia, and Alfie as well in vengeance. Vera is portrayed as being the Collector because the Collector sent the same message Vera sent to Jasper.
Victor's sight returns in time for him to find an important passage on the Mask of Anubis. Jerome goes to visit his father, but he finds that Poppy has beaten him to it. Sibuna finds a crawl tunnel, and it is implied that it could that be the only way through to the next task. When Alfie enters it, it collapses, trapping him. Amber tries to rescue Alfie from the crawl tunnel; however, she fails, and Fabian has to save both of them. Later, Amber and Alfie break up. Victor spots the amulet around Amber's neck and confiscates all pupils' jewellery by invoking an obscure school rule. Now, the tunnels are his to explore.
Victor hits a dead end in the tunnels. When Victor returns from the tunnels, Vera gives the Book of Isis, which she had found in the desk located within Robert Frobisher-Smithe's study, to Victor. However, she steals the most important chapter from the book first. Sibuna tries to exhaust Victor by keeping him awake all night. He falls into a deep sleep so they can steal the amulets from him. Jerome looks for his dad's gem but fails to find it. While Nina and Fabian try to take the amulets off Victor, he nearly awakes from the sound of Nina cutting the amulets off him.
Jerome informs Mara of his father's mission and tells her that his dad wants him to find a special gem in a suit of armor. When Nina enters the tunnel, she finds a lever and pulls it to open the next door in the tunnels. Back by the entrance, the wall folds in on itself and leads deeper into the tunnels. The kids arrive at their next challenge: a giant spider web. While searching the kids' rooms, Vera gets a hold of the extra amulet hidden in the dollhouse. While Nina, Fabian, Alfie, and Amber are down in the tunnels, Eddie and Patricia perform chores for Victor. Mara tells Jerome that the armor is hidden in Mr. Sweet's office. Jerome inadvertently convinces Alfie to create a distraction to lure Mr. Sweet out of his office by letting a goose through the hallway. While searching for the gem, Jerome accidentally causes the armor to fall and hears Mr. Sweet coming back to his office.
Alfie's goose is led into Mr. Sweet's office, and it swallows the gem. Victor decides to forge a fake amulet so that when the kids look to find the extra amulet, they will not realize that Victor stole it. Trudy tells Mrs. Andrews her concerns about Vera. Eddie and Patricia run off to play American football, and Patrica loses her amulet. Joy asks Fabian to go on a date, but he does not give a definitive answer. Victor calls everyone inside to check the house after a suspicious pet food package arrives in the mail. Victor puts the fake amulet inside the dollhouse. Patricia realizes her amulet is missing and goes to look for it. While she has no luck, someone finds the amulet and takes it
Mrs. Andrews asks Mara to investigate Vera for a "profile" on the website. Jerome is delighted when the goose passes the gem, until Mara drops it down the sink. Patricia wears the fake amulet to the tunnels, and she is blinded. The others go ahead into the tunnels without her. Patricia hears someone coming into the tunnels and blindly searches for Sibuna. As Sibuna explores the spider web task, Patricia arrives to warn them that someone is coming. As they hide, Victor reaches the web and is stung by the web. Mr. Sweet tells Mara that Jasper was the one who secured Vera's job.
Jerome may have lost the gem, but he now has Patricia's amulet, thanks to Poppy. Nina and Fabian steal the gem from Vera's room and trade with Jerome to secure the amulet. Later, Nina sees a riddle in the dollhouse telling her to follow the "silver thread of fate." Jerome has the gem, but he faces another complication: the shield is missing. Meanwhile, Eddie overhears Patricia telling Joy that she likes him. Mara investigates Vera's room for information, but Vera comes inside and she threatens Mara who now fears Vera. Mara also stumbles upon the missing chapter of the Book of Isis, which then finds its way into Victor's hands. And Sibuna discovers a sinister clue to the spider web task, including a new riddle and a giant life-like spider
Victor is translating the Book of Isis, but it is not as easy as he had hoped. Eddie tries to get Patricia to admit that she likes him. Fabian and Joy go to a movie. Nina is hurt by Fabian's action and decides that they should go to the tunnels to solve the spider web task without Fabian, but it is a decision that she will regret after Alfie's life is put in danger. Eddie and Patricia misbehave in class, but it is Patricia who Mr. Sweet punishes. Alfie and Jerome realize that if Jerome wants the shield in which the gem belongs, he will have to win it back from a rival school. Meanwhile, Mara figures out that Vera's resume is all lies, and Nina learns Senkhara's name. Sibuna finally passes the spider web task, opening a door, which then starts to close. As it closes, Nina walks inside, knowing that this is the only chance she has to get closer to finding the mask.
As Mara gathers evidence against Vera, Sibuna completes the web task after Fabian puts the larger spider in its place. They move on to the next task where they must follow the clues on the wall and pick the right liquids and pour them into six different tubes on a lion's head, which will free the glue stuck to the door into the next tunnel. Meanwhile, Victor realizes that the latest task is one that he can solve himself and takes the lead in the race for the mask. Jerome needs help to win back the Frobisher Shield, but he never expected for it to come from Amber, who has been a ping-pong champion in the past. Nina and Fabian see Victor with some chemicals and become suspicious. Patricia calls Eddie Mr Sweet's pet and best friend. After Patricia leaves, Eddie convinces Mara to upload her report exposing Vera on the school website
Alfie is delighted when Jerome makes him ping pong coach. Vera is upset about Mara's article. Patricia's mocking causes Eddie to plan an epic prank on Mr. Sweet. In the tunnels, Victor completes the task and moves on to the next task. Senkhara becomes furious and causes Nina's mark to burn. Mara and Vera go head to head in a hearing to establish the truth of Mara's claims. But Mara does not realise that her key witness is also Vera's. Fabian thinks that they have solved the potions task, but Nina is suspicious that Victor may have beaten them to it. Eddie's prank on Mr. Sweet backfires on Mara, and she is expelled
A shocked Mara is expelled, while Jerome fires "Coach" Alfie. Vera has secretly bribed her witness - and Trudy is still suspicious. Mara doesn't get expelled but can't work for the website anymore and Mrs. Andrews takes the punishment and leaves the school. Patricia learns a huge secret about Eddie and Nina gets some bad news about Gran... Jerome's tournament goes badly - will he fail his dad? As Victor is getting ahead, Senkhara is getting angrier. She yells at Nina for visiting Gran instead of working through the tunnels. Nina gets upset and says that Senkhara doesn't exist and walks through her. Senkhara then tells Nina her punishment "will be to punish." The next day, Nina's innocent words to her friends are twisted by Senkhara into hexes. Nina gets a vision about herself turning into Senkhara and the Sibuna gang is running away from her
Alfie accidentally reveals Jerome's opponents have used crooked balls and then helps him win the match. Victor explores the next task and is deafened by a powerful klaxon. Nina realises that it's her words that have hexed her friends. Senkhara tells her the punishments will last until the task is complete. Patricia loses her voice, Alfie turns into a little kid, Fabian loses his memory, and Amber is turning old. The Sibunas are alarmed that Victor has his own amulet. Mrs. Andrews gets replaced by a teacher named Mrs. Valentine. Due to Fabian being hexed with memory loss, he calls Joy "Pam" which sends her running out in tears confirming her crush is indeed crushed. Eddie tries to speak to Patricia about his feelings for her, and Patricia confirms her feelings with a kiss while Joy walks in on them. Later, in the tunnels, Alfie plays on the horns, but he gets the tune wrong. The klaxon sounds again, but this time, the ceiling cracks and begins to collapse
The Dollhouse tells the Sibunas the tune for the task: an ancient Egyptian song called the Song of Hathor. But no one still alive has heard it... Meanwhile, Amber agrees to be the face of the school in a new commercial - despite ageing in fast forward - and Mara hears that Mick has a new girlfriend and decides to make him jealous by pretending to date Jerome. The Sibunas are shocked as Alfie's rejuvenation curse accelerates and turns him into a 7 year old. Meanwhile, Patricia gets stuck in the bathroom and accidentally stands Eddie up. Nina finds out that Victor has some information about the Song of Hathor. Jerome's pretend relationship with Mara comes to an end and Victor and Vera hatch a plan to steal an exhibit from the Library, which Fabian overhears them discussing.
Fabian tries to tell Nina about Victor and Vera's plan but forgets. Vera steals the Ox Bell from the exhibition. She escapes without getting caught, but Vera's cardigan gets caught on glass and Trudy finds the piece of fabric. Later on, Fabian decides to go to the library and sees an object missing. Trudy finds him and thinks that he had stolen the object. Meanwhile, it's Jerome's turn to babysit Alfie while Nina is forced to ask Senkhara for help with the task and she plays the song to Nina. The Sibuna gang go down into the cellar and try the horns task again. It doesn't work. And then Nina makes a terrifying discovery in her bedroom. Fabian's memory loss leaves him unable to give Trudy an alibi. Then he finds his note predicting Vera's theft. Can he convince Trudy? Eddie is shocked when Patricia tells him she never kissed anyone before him. And just as Nina is getting over the speed at which Amber is aging, Alfie turns into a baby
Fabian is now unable to remember his own name - he even forgets who Nina is. Vera plants the ox bell in his room, but hears Nina and Fabian coming so she hides in the closet. They find the ox bell and take it to the tunnels, completing the task, curing them all. But their celebrations are short lived as Victor and Vera hatch their plan, leaving Nina and her friends to walk into a trap. Victor and Vera's plan backfires, leaving the Sibunas to return the Ox Bell to the Library. Alfie, Fabian and Nina explore the next task tunnel and realize that if they finish this task, they'll find the mask! Patricia has to admit to her friends that she has been keeping a big secret, her twin sister Piper. Upstairs, Trudy gets closer to the truth about Vera. But has she gone too far?
A riddle in the next task hints that it is the final chamber before they reach the Mask. The Sibunas need to find six mysterious reflectors. The dollhouse shows the dolls at Victor's office, so the Sibuna go and try to find a reflector... which they couldn't find. Eddie decides to kiss Patricia again, but actually kisses Piper instead! Victor overhears Nina and Fabian talking about the final task; he does have a reflector... his father's watch. And Trudy has been kidnapped! But she leaves a strange note for Jasper. Piper (as Patricia) acts kind to Alfie, since she has a crush on him, making Alfie fall in love with Patricia not knowing that it's really Piper. Victor has the first of the reflectors and Nina and Amber work out that the next one is in Sarah's music box. Jerome is worried when Jasper starts to obsess over the Gem. When Piper (as Patricia) is kind to Eddie, he starts to question his relationship with Patricia. Mr Sweet asks Eddie and Patricia to dinner. Strangely, Patricia accepts. She tells Piper to go as her and tells her that Mr. Sweet is Eddie's dad... which Joy overhears. Jasper takes the Gem and hides behind the stage when he hears Jerome coming. Jerome realizes that the Gem is missing and tells Mr. Sweet. Meanwhile, Jasper places a fake Gem back and hides. When Jerome comes back with Mr. Sweet, the Gem is back and Jerome is determined to find out who had tried to steal it.
The race is on to find all of the reflectors - and the clues lie in an incomplete Zodiac chart. Mr Sweet doesn't believe the gem has been stolen. Looks like Jerome's on his own now... Meanwhile, at the restaurant, Piper turns up posing as Patricia. Patricia decides to keep an eye on Piper. Sweet and Eddie are fooled that is, until Eddie and his dad see both Piper AND Patricia standing next to each other... Nina realizes Victor has his own copy of the Zodiac but his is more complete! Amber makes a copy but Fabian can't decipher any of the symbols. Meanwhile, Jerome hacks Jasper's computer and proof that he is working for the Collector and then he finds a coded call for help from Trudy...
Patricia feels that Piper is cramping her style. Eddie feels bad that he had kissed Piper accidentally, but Piper tells him it's best not to tell Patricia. Jerome learns from Jasper that Trudy has been kidnapped by the Collector and he will need to find a Frobisher Smythe artifact to buy her back. Victor decides to invite Gustave for dinner and Alfie decides to volunteer for the entertainment by doing magic.The Sibunas discover a secret door in the task chamber - but will only open to a certain amulet... which happens to be Victor's. Alfie and Piper get closer, but an argument with Patricia makes Piper reconsider her future. Jerome's search for Frobisher heirlooms leads him to Nina and Amber's room, where he finds Sarah's dollhouse. Gustave comes for dinner, and Alfie does his trick by taking Victor's amulet and making it "disapear". After Alfie breaks the amulet into pieces, Victor decides that the real amulet is up his sleeves... which leads to Alfie dropping the other piece of cloth from his sleeve... will Sibuna get their amulet back?
The Sibunas are delighted when Alfie reveals Victor's amulet in one piece - all part of the trick. Then Nina realizes that someone had moved the dollhouse and decides to hide it. Piper says goodbye and gives Patricia her necklace. Eddie comes and sees Piper's necklace on Patricia and belives that she's Piper and tells "Piper" that he feels bad that he still didn't tell Patricia about their kiss. Patricia's devastated when Eddie lets slip that he kissed Piper. Jerome believes Vera has stolen the dollhouse and Nina and Fabian realize that Vera is after the mask. Joy pairs Eddie up with Mara to do a story on the revamped school website. Victor and Vera realize Alfie has tricked them and that he has the real amulet. The Sibuna gang opens up the secret door using Victor's amulet, leading them to the library. Fabian overhears Jerome and Jasper plotting something in the library and starts to think that Jasper might be an enemy. Patricia talks to Eddie in Mr. Sweet's office and accidentally turns on the loud speaker; she mentions that Eddie is Mr. Sweet's son and the entire school hears her.
Eddie thinks that Patricia on purposely pressed turned the speaker on to get revenge on Eddie. The race is on between Victor and the Sibunas to find the missing falcon reflectors. Victor doesn't finds anything in Alfie's room. Jasper brushes Fabian off when he's confronted about his secret talks with Jerome and Fabian believes it. Nina finds another reflector in the kitchen: a goblet. Eddie's shocked when his article research reveals a video image of Senkhara. He shows Mara and they start a ghost hunt, setting up cameras in the house. It does little to ease Patricia's jealousy. Nina realizes that Sarah's doll is a falcon reflector, just as Jerome steals it for Jasper. Jasper accidentally tells Jerome where he's meeting the collector and Jerome decides to follow. Hiding, Jerome sees Vera and another man with her. The Collector doesn't want the doll and throws it on the ground but then, Jerome moves making a sound and Vera comes over and tries to see if Jasper had brought anyone with him... will she find Jerome?
The Collector rejects Jasper's offering of Sarah's doll and Vera doesn't see Jerome. But then Vera realises that Victor needs its glass eye - it could be the next reflector! The Sibunas find out that there's a reflector in a moasaic... that Trudy has throw out. Fabian learns from Joy that it's in the library and the Sibunas recover it. Amber forgets to lock up the dollhouse and Jerome gets his hands on it. The only thing is that he doesn't that Eddie and Mara's camera had recorded the whole thing.. The Sibunas find their third reflector in the library, but Fabian now knows Jasper has been lying to him. While getting out of the tunnels, Patricia sees Eddie and Mara and yells... causing them to wake up. The quickly get a picture of their "ghost" (which happens to be Amber) during their cellar stake out. With photographic evidence and Mara's theory that their ghost is the "Unknown Ruler", their story could destroy the Sibuna's secret mission! Nina realises that the dollhouse is missing and Jerome gives the dollhouse to Jasper who calls the Collector about it. The Collector takes the dollhouse and doesn't bring Trudy back... getting angry, Jasper takes his hood off and Jerome is shocked to find out who the Collector is.
After Jasper rips off the Collector's hood, Jerome learns that Rufus is back! The Sibunas learn that Eddie had backup files on a USB drive, even though they tried to infect the picture files on his computer, so Nina dispatches her friends on different missions; Fabian has to try and convince Joy not to run the story, Patricia must apoligize to Eddie, and Amber and Alfie must steal Eddie's camera. Jerome and Jasper follow Rufus and Jerome tells Jasper who he is, and they fall back. Vera finds another reflector; a piece of stained-glass from the window in her room; Joy agrees not to run the story, on the condition that Fabian kisses her, Nina overhears it and is dismayed until Fabian tells Joy he can't do it and reveals his true feelings for Nina, but Joy decides not to run the story anyway; Eddie reconciles with Patricia. Alfie and Amber steal Eddie's camera and learn that Jerome stole the dollhouse and the two confront him. He then reveals Rufus is alive and that he his blackmailing Jasper with the threat of harming Fabian and Vera is working for him and they find out she is a double-agent; the Sibunas and Jerome try to tell Victor this but he doesn't believe them. Amber and Patricia then overhear that Victor has three reflectors and Vera overhears that the Sibunas have the remaining three. Rufus then visits Trudy and interrogates her about the dollhouse, but when she doesn't give enough information, he tells her he no longer needs her, much to Trudy's dismay.
The kids persuade Jasper to offer Rufus the replica mask from the library while they rescue Trudy; however, Alfie and Nina have to take a test leaving Amber, Jerome, and Fabian to rescue Trudy. But they are locked in the barn by Vera and Patricia and Nina can't rescue them because Senkhara traps them wanting the two to focus on the quest for the mask. Alfie manages to rescue the kids but accidentally smashes the dollhouse and knocks Trudy unconcious who forgets everything about Vera and the Collector. Senkhara promises to help get the three reflectors back by slowing down Victor's progress; Joy misinterprets advice from Ms. Valentine and decides to write a rude post about Nina on a blog by an anonymous blogger named "Jack Jackal"; Rufus meets with Vera and promises to share the power of the Mask of Anubis with her; Victor has a dream of Vera getting marked by Senkhara, but when she doesn't show up to make breakfast and Victor tries to find Vera, he makes a terrible discovery...
When a poisonous article about Nina appears on the school website, speculation is rife about the identity of the school's phantom blogger. In order to save Vera, Victor hatches a plan and leaves his reflectors in his office, knowing that Sibuna will snoop around and find them when he goes out. The gang succeeds in finding the objects, and Fabian also finds Victor's completed zodiac, along with a list of where he believes the remaining reflectors are. Alfie and Amber go into the attic to retrieve the reflector from the stained glass window but, unaware that Vera is still catatonic nearby (concealed beneath a blanket by Victor), they accidentally reveal the existence of the passage between the tunnels and the library. Meanwhile, Mara knows that Jack Jackal did not write the hateful blog on NIna, as she herself is Jack Jackal. After prodding Joy for information, Joy hesitantly admits that she wrote the blog. Vera now bears the mark of Anubis and the Sibunas have all the reflectors, but they run out of time and the reflector stands disappear. What will they do now? Fabian finds out that Joy wrote the article and gets mad. Gran's condition deteriorates and Fabian makes a horrific discovery at the hospital: Gran is the time piece and she has the mark of anubis
Joy tries to apologize to Nina, who is upset over Gran being cursed, but the gang isn't having it and they freeze Joy out. Sibuna realizes that in order to complete the task, they will have to borrow a "Sibuna temp" to hold the sixth reflector, so Patricia hatches a plan to bring a blindfolded Eddie into the tunnels under the pretense of a "date." Sibuna and the oblivious Eddie manage to complete the task and enter the final chamber. However, the Mask is nowhere to be found and Fabian determines that in order to pass on, they must play the ancient game of Senet. Jerome is suspicious of Jack Jackal's latest article about a father-son relationship, and confronts Joy about it. Joy allows Jerome to think that she wrote the article, and that she knows Jerome's personal information regarding his father because Mara told her. However, after a hurt Jerome confronts Mara about it, the truth is revealed. Mr. Sweet permits Mara to write for the blog once more and Jerome and Eddie reveal to all their classmates that Joy wrote the hateful article about Nina. Rufus discovers he has a phony mask and threatens Vera to get him the real one.
The Sibunas realize they must play the ancient Egyptian game of Senet - and the stakes are high. Joy is still getting a hard time because of Mara, so when Mr Sweet tells her to enter Mara in the blog competition, Joy makes other plans. Trudy is having strange dreams - could her memory be returning? Victor and Vera secretly practice Senet in his office, while the Sibunas meet Jasper who tells them Rufus knows he's been tricked, and he does it soon after the Sibunas find the rules on a mismatched tile on the library floor. Jerome finally makes his move on Mara, only to discover she's still not over Mick. Down in the tunnels, disaster strikes when Nina moves to the wrong square and the floor gives way beneath her.
The Sibunas are reeling at Nina's disappearance and must cover for her both at school and to a suspicious Victor and Vera at home, as well as keeping a furious Senkhara at bay. Joy enters her article into the contest, but Mara thinks that her article was entered. Eddie knows that Joy had lied to Mara and tells Jerome. Nina wakes to find herself in an underground cell, and she is not alone... A distressed Fabian goes to tell Mr Sweet everything, but then while Mr Sweet isn't in the office, he hears Nina calling from underneath realising that Nina is still alive. Patricia tries to be more couply with boyfriend Eddie, which only serves to alarm him. Nina sees Victor Rodenmark Sr.'s ghost. Under pressure, Fabian makes a wrong move at Senet and things look even worse for the Sibunas.
Alfie manages to escape the falls thanks to Patricia. Eddie and Jerome reveal that Joy didn't submit Mara's article to the web competition. The gang are left shaken after Alfie's near miss and Fabian recruits Joy as strategist - they've got to win this game somehow. Nina learns that every chosen one has a special champion to protect her. Trudy calls a doctor to help her get her memory back, but a desperate Vera decides to intervene by canceling Trudy's real appointment and asking someone to pretend to be her doctor. Fabian sees Victor playing senet. Alfie and Amber decide to spy on her and the doctor and find out that the "doctor" placed fake memories into Trudy's head and that Vera wants to do the same to Sibuna. Meanwhile, Joy tries to get to grips with the Senet Task at the library when a secret man who was Trudy's doctor visits Jasper and takes off his mask...
Joy realises that Trudy's doctor was Rufus. Mara's confused - does she have feelings for Jerome? Vera follows the doctor's instructions to try and control the Sibunas, not knowing that they are playing along in order to find out how much Victor knows about Senet.
