You ever hear the one about the cop, the songbird, the psycho and the mafia princess? HARLEY QUINN: BIRDS OF PREY is a twisted tale told by Harley herself, as only Harley can tell it. When Gotham's most nefariously narcissistic villain, Roman Sionis, and his zealous right-hand, Zsasz, put a target on a young girl named Cass, the city is turned upside down looking for her. Harley, Huntress, Black Canary and Renee Montoya's paths collide, and the unlikely foursome have no choice but to team up to take Roman down.
