The rock gods of Jackson Tennessee

In 1989, outcasts Marty, Jonny, Lenny, and Doug start a band called the Rock Gods, and they can't believe their luck when they get to chance to open for local rock legend Tommi Tungstun at his upcoming gig. But there's one thing none of the boys expected: mutated monster pigs. Soon, it's up to the four teens to save their town from total destruction.
