Batman is dead, and Gotham City has been left without the Dark Knight to protect it. Bruce Wayne's adopted son, Turner Hayes, is framed for the Caped Crusader's murder, along with the children of some of Batman's enemies.

With hard-charging District Attorney Harvey Dent and the GCPD hot on their trail, Turner relies on his best friend Stephanie Brown and unlikely Batman sidekick, Carrie Kelley, for support.

Before long, the Knights soon discover a larger, more nefarious force at work within Gotham City. The team of mismatched fugitives must band together to become the city's next generation of saviors.
