Ordinary teenager and rabid comic-book geek Dave Lizewski captures the imagination of the public when he becomes the no-nonsense vigilante, Kick-Ass. After he teams up with the fearless father-daughter crime-fighting duo, Big Daddy and Hit-Girl, the three work together to take down the criminal empire of local Mafioso Frank D'Amico. But when D'Amico's son Chris is reborn as Red Mist, the showdown between the forces of good and evil will force Kick-Ass to live up to his name, or die trying.
