Summary:

Someone is targeting Batman’s allies in Gotham—young and untested heroes who model themselves after the Dark Knight but don’t yet have his training or resources. With the help of Batwoman, the Caped Crusader recruits these young vigilantes, training them to be a team worthy of Gotham’s biggest threats.
Red Robin, Spoiler, Orphan and Clayface are the first heroes to get recruited. But can a team inspired by Batman and trained by Batwoman take on an entire anti-vigilante army? Or will Batman’s vision of a team of Bat-Heroes go down in flames?
