The Clowns are the hottest new rock band on the scene, with a wild stage show that features simulated acts of violence and dismemberment. Outfitted identically in theatrical makeup and skin-tight outfits, not even their biggest fans know what they really look like or which one is which. One night after a Clowns performance, a drug dealer is found stabbed to death in the alley outside the theater, and the police believe that one of the group's crazed fans took their bloody stage antics a little too seriously. When a private party for the band results in a pile of mutilated groupies, the suspicion falls directly on the Clowns and their road crew. Could the killer be the hotheaded roadie, or maybe the pill-addict drummer? The introverted stagehand who secretly puts the band's makeup on to meet girls? The levelheaded manager who left behind a life of religious dogmatism for the rock & roll world? Or the guitarist who feels conflicted about the sick show the Clowns put on, and wonders just what is wrong with their fans? A young juvenile delinquent with a bad rap sheet is recruited by the police force to infiltrate the band's inner circle and search for clues to the maniac's identity, but she soon finds herself a target. In between the drug-fueled bashes and loud, pulsating rock, the killer stalks the bowels of the theater, waiting for another victim to destroy.
