Catwoman, Poison Ivy and Harley Quinn have a new agenda that's all their own, and they'll use any means necessary to pursue it. The three villains are tired of playing by other people's rules, regardless of which side of the law they're on. But can they get along and work as a team? And who will get hurt along the way?
