But he is out of his depth - a fearless and highly trained father-daughter crime-fighting duo, Big Daddy and Hit Girl, have declared war on New York mafioso, Frank D'Amico. As Kick-Ass and his newfound friend, Red Mist, get drawn into their no-holds-barred world of bullets and blood, the stage is set for a final showdown in which the DIY hero will have to live up to his name...or die trying.
