The women will not just be fighting for the hell of it, but to protect young Cassandra Cain (Ella Jay Basco,) who, comic book aficionados will know, is one of the various Batgirl incarnations.
In Birds of Prey, Harley Quinn has left the Joker (Jared Leto) and is trying to make things work alone with her friends.
However, when she discovers a girl Cassandra, who has accidentally taken something from a seriously dangerous mobster, she forms a band of ladies to help her fight back and show that sisters really are doing it for themselves.
Soon she realises those women are all trying to fight for themselves, and the only way to win is to team up.
