In the aftermath of Batman's disappearance, Kate Kane must overcome her demons to protect Gotham City by donning the avatar of Batwoman.
After years of training, Kate Kane returns to Gotham to become a member of her father Jacob's security team, the Crows. Batman disappeared three years ago, and Gotham is just now beginning to adjust to his absence. When the Wonderland Gang abducts Kate's former lover Sophie, Kate discovers a secret about her cousin Bruce that will change her life... and the lives of everyone in Gotham.
Back in Gotham, battling Alice and the Wonderland Gang from the shadows, Kate Kane continues to be haunted by the events surrounding her sister’s death 15 years earlier. While the city holds on to hope that Batman has returned, Jacob Kane and the Crows up the stakes trying to take down the villainous crew. Kate continues to look to Bruce Wayne’s legacy for guidance as Luke Fox inadvertently gets pulled into Batwoman’s vigilante heroics. Sophie and Kate are forced to team up, while Mary finds herself in Alice’s crosshairs.
As the city waits impatiently for another visit from who they think is Batman, Alice continues to taunt Kate with a secret but also sets her sights on Jacob and Catherine. Kate is visited by Tommy Elliot, a childhood friend of her cousin who has finally realized his lifelong dream of being wealthier than Bruce Wayne and throws a party so all of Gotham can celebrate his success. Mary gets an unexpected new bestie when Sophie is assigned to protect her. Luke and Kate work together to uncover who may have taken a valuable weapon from Batman’s arsenal. And as Batwoman faces a new enemy, Kate realizes she must either walk away from her new role or fully embrace the mantle as Gotham’s new hope.
A new villain with an eye for all things that sparkle drops in on the city. Kate attempts to find a balance between her personal life and her new role as Gotham's guardian. Catherine has an uncomfortable encounter with Alice who always seems to be one step ahead of the Kane family. Batwoman pays fangirl Mary a visit to ask for a favor. Meanwhile, Jacob and Sophie try to piece together who was after their prisoner. Luke continues to finetune Batwoman's arsenal of weapons as the pair track their unwelcome visitor and discover she has more sinister plans than snatching shiny objects.
Alice takes Kate down the sad, winding road of her life in the days after the accident as Jacob and Sophie attempt to track them. Mary has an argument with Catherine which sends her looking for Kate at Wayne Tower, but instead, she becomes unwelcome company for Luke.
A disturbing death has Gotham reeling and the city reaches out for their new vigilante hero. Luke confides in Kate, while Sophie asks Jacob for a special assignment. Alice continues her nefarious plot against the Kanes, with Catherine being a conduit to part of her plan. Batwoman pays another visit to Mary.
