An average teenager decides to take his obsession with comic books as inspiration to become a real-life superhero. He picks a nickname - Kick-Ass - assembles a suit and mask, and gets to work fighting crime. There's only one problem - Kick-Ass has absolutely no superpowers. When he meets a pair of crazed vigilantes - 11-year-old sword-wielding dynamo Hit-Girl and her father Big daddy - Kick Ass's life changes forever. Together with another fledgling superhero, they forge an alliance that will soon be tested by the local mob boss. A twisted, funny, and high-octane adventure.
