On the verge of starting fresh, Marius is dragged back into the role of Pete Murphy when two thugs-believing he's Pete-threaten to kill the Bernhardts if he doesn't take them to Pete's estranged mother and the millions she stole from their employer. Now Marius must tread a dangerous line to find her and protect the family, all while keeping up the Pete con.
Marius sees an opportunity when he is seized by two mercenaries searching for Pete's mother Maggie and the eleven million dollars she stole from their employer. Meanwhile, Audrey and Otto deal with the fallout from Winslow's death, and Julia struggles to keep her promise to Dockery.
Marius and Marjorie take on the prison system in an attempt to free Pete. Taylor meets a talented NYPD detective who has come to Connecticut to investigate Winslow's death, while Audrey tries to conceal her connection to the crime. Otto and Sam do a favor for Irish Moe.
Marius tries to contain the newly emancipated Pete and pump him for information on Maggie. Frank and Joe tighten their grip on family surveillance. A formidable associate of the dead hit man appears, wanting to know what happened to his disappeared colleague. Carly investigates further into Marius Josipovic. Taylor struggles to keep Roby and Carly away from the truth of the Winslow case.
After sending Pete on a fool's errand, Marius leads Frank and Joe to Maggie's suspected hideaway in the psychic town of Rosedale. Taylor and Roby head back to the scene of the crime. Otto becomes hostage to the hitman's associate. Julia works a lead to find Lance and force him to cooperate in a plan to help her launder money.
Eluded by Maggie and under threat of being taken to Luka, Marius desperately tries to evade Frank and Joe. Just as Julia discovers the solution to her money problem, she finds herself in deeper trouble. A new development in the Winslow investigation starts to turn Roby in Audrey's direction. Carly seeks a connection to her parents and gets more than she bargained for.
Maggie's return to the Bernhardt homestead leads to family tensions resurfacing. As Marius tries to pry the location of the money from Maggie, they are grabbed by FBI agents. Taylor and Shannon's relationship begins to drift, just as he sparks a connection with Roby. Frustrated by their inability to find his money, Luka shows Frank and Joe that he's not playing games.
The location of the money revealed, Marius makes a bold move to snatch it all for himself, but Maggie and Luka are not so easily fooled. Taylor makes plans to frame the hitman for Winslow's murder. Carly turns to Maggie in search of an otherworldly connection to her parents. Julia's new bondee proves more challenging than anticipated. Otto and Sam find that their Colin troubles are far from over.
Jealous of Marius' relationship with the family, Pete threatens to implode the heist unless he is granted a special request. Otto and Sam retrieve the Proclamation, but discover the larger threat Colin poses to Julia. Julia, Taylor, Otto, Carly, and Audrey disclose the urgency of their troubles to each other, and Audrey's suspicions about Maggie and Marius come to an ugly head.
After Marius' "Roosevelt Buffalo" plan works too well, the heist's fate is left in Pete's hands. Carly and Audrey investigate Marius and Maggie's motives for returning to the family. Julia enlists the aid of Otto, Sam, and - much to her chagrin - Lance in protecting Valerie from Colin. Taylor takes the final steps to frame the hitman for Winslow's death, and hopefully save Audrey.
Marius' plan implodes as it becomes clear he was wrong about the money's location, and must now face Luka's wrath. Julia, Valerie, Otto, and Sam square off with Colin and Ayawamat at the storage facility. Audrey discovers the danger of Luka and rushes to protect the family. Taylor settles accounts with Roby and Shannon. Maggie gives Carly new information about what happened to her parents.
