The year is 1978: the KISS Army is at the height of its powers. Enter card-carrying members Hawk (Edward Furlong), Trip, Lex, and Jam, four Detroit teenagers who will do anything to go to the KISS show. As we follow them through one day, we see the insane lengths these shaggy-haired young chaps will go to in order to see their favorite rock-and-roll superheroes at a Detroit arena. The band themselves show up in full regalia as their 1978 selves, but Natasha Lyonne steals the show as a sweet young disco mama.
