The year is 1986. Big hair, big bands, big everything. In a small suburban communtiy, we meet our motley crew. Tamara Sparkler, a smart-as-a-whip bassist, Sally Summers, a rough 'n tumble vocalist, Trixie LaVerne, one of the rhythm guitarists, Rachel "Rainbow" Rocket, the other guitarist, and Christina Peretti, the hyperactive drummer. This crew's name is Twin Turbos, a garage band dedicated to Judas Priest. When Tammy's overbearing mother scolds her for not studying and playing "unholy music," she is torn from her friends after the tickets to Priest's upcoming concert are burned. Embarking on a journey entailing drugs, violence, and just plain stupidity, our girls find the opportunity to get to their final destination: Front row at a Judas Priest concert.
