As Ryan Wilder's Kryptonite wound grows more severe, it hinders Batwoman's ability to protect Gotham. Growing interest in reproducing the serum from the Desert Rose puts Mary's and Commander Kane's lives in danger. Meanwhile, Alice's reunion with a fellow Coryana inhabitant presents unexpected complications.
Kate Kane never planned to be Gotham's new vigilante. Three years after Batman mysteriously disappeared, Gotham is a city in despair. Without the Caped Crusader, the Gotham City Police Department was overrun and outgunned by criminal gangs. Enter Jacob Kane and his military-grade Crows Private Security, which now protects the city with omnipresent firepower and militia.
Years before, Jacob's first wife and daughter were killed in the crossfire of Gotham crime. He sent his only surviving daughter, Kate Kane, away from Gotham for her safety. After a dishonorable discharge from military school and years of brutal survival training, Kate returns home when the Alice in Wonderland gang targets her father and his security firm, by kidnapping his best Crow officer Sophie Moore. Although remarried to wealthy socialite Catherine Hamilton-Kane, who bankrolls the Crows, Jacob is still struggling with the family he lost, while keeping Kate - the daughter he still has - at a distance. But Kate is a woman who's done asking for permission. In order to help her family and her city, she'll have to become the one thing her father loathes - a dark knight vigilante.
With the help of her compassionate stepsister, Mary, and the crafty Luke Fox, the son of Wayne Enterprises' tech guru Lucius Fox, Kate Kane continues the legacy of her missing cousin, Bruce Wayne, as Batwoman. Still holding a flame for her ex-girlfriend, Sophie, Kate uses everything in her power to combat the dark machinations of the psychotic Alice, who's always somewhere slipping between sane and insane. Armed with a passion for social justice and a flair for speaking her mind, Kate soars through the shadowed streets of Gotham as Batwoman. But don't call her a hero yet. In a city desperate for a savior, she must first overcome her own demons before embracing the call to be Gotham's symbol of hope.
