It's 1989 and Marty Ward, Jackson Tennessee's number one juvenile delinquent, never wanted to join the Rock Gods. After all, who wants to play with nerds like Jonny, Lenny, and Doug? But after the high schoolers stumble into the gig of a lifetime-opening for local rock legend Tommi Tungstun-the four outcasts must put aside their differences and play together if they want to achieve their dreams of fame, freedom, and popularity. Standing in these future superstars' way are: their parents, their teachers, a school full of jerks and bullies, a townful of bad bosses, sanctimonious preachers, corrupt politicians, each other, and a rampaging horde of mutated monsters tearing through Jackson and eating everything in their path.
