In season three of “Batwoman,” Ryan Wilder has shed her parole for the Batsuit and her van for the Batcave to carry out the legacy of Batwoman and protect Gotham’s underserved communities. Her journey continues as she and the Bat Team focus on finding Batman’s scattered trophies, a collection of objects seized from Gotham’s most infamous villains, before they land in pernicious hands.
As Batwoman continues to keep the streets of Gotham safe, Batwing joins in on the action, but Luke quickly realizes he hasn't quite mastered his suit. When Ryan pays Alice a visit to ask about the bombshell she dropped, Ryan must decide if she should go down the rabbit hole of her past. As Mary prepares to finally graduate from medical school, she feels the absence of her family more than ever. When an Alice admirer stumbles upon one of the missing Bat Trophies, Gotham and the Bat Team get mixed up in the madness, culminating in a shockingly gruesome graduation... and an equally shocking new partnership.
When a new incarnation of Gotham's swamp slumming Killer Croc surfaces and starts racking up a body count, the inaugural team-up of Batwoman and Alice is put to the test. But Alice isn't the only unwanted intrusion into Ryan's life when Jada Jet shows up at Wayne Enterprises, insisting on meeting the company's new CEO. Luke and Mary's relationship is strained under the weight of a secret Luke is keeping, while Sophie finds herself becoming part of Ryan's inner circle.
An unfortunate incident in downtown Gotham alerts Batwoman and the Bat Team that another missing trophy has made its way into the wrong hands. Meanwhile, a new member of the Jet family surfaces when Marquis Jet makes a not-so-subtle entrance, interrupting a very personal moment between Ryan and Jada. Batwing must decide if he's ready to suit up again, and the Hippocratic Oath forces a strained sisterly moment between Alice and Mary.
When Ryan makes Gotham's "30 Under 30" list, Luke worries about how Marquis's involvement in Ryan's rising popularity as Wayne Enterprises' acting CEO will land with Jada. Mary returns from a late night out not feeling quite herself, while Alice's hallucinations grow stronger. And when Sophie's sister, Jordan, goes missing, she and the Bat Team quickly realize that Freeze's missing weapon hasn't been fully contained.
Ryan asks Sophie to accompany her to a dinner at Jada's to do recon on what her estranged mother knows about Wayne Enterprises, but the evening takes a turn when an uninvited guest drops in on the intimate gathering. As the terrifying evening unfolds, Ryan witnesses another side to Marquis and her mother.
