Dexter, Denny, Bitsy, and Lummox stop at a local neighborhood bar for a few drinks when the bartender becomes irritated with their shenanigans and orders them to be quiet to which they respond by beating up the owner.
At a corner coffee shop, the overly zealous teens engage in a bloody fist fight with another teenager, named Doug (Rodney Bedelle), who used to know Dexter and was part of his gang before walking away years ago.
With no witnesses willing to come forward on fear of retribution from the Destruction crew, and with circumstantial evidence to hold him on, the police release Dexter, only giving him a warning to keep out of trouble.
A confused and senile old woman sees the rumble and calls the police, but the gang flees, and Doug unbelievably gets arrested for fighting with the boys.
The four teenyboppers attack and beat up the boy, while the young woman is gang raped and afterwards, both her and her boyfriend are bludgeoned to death by the sadistic youths who withdraw from the scene of the crime.
Dexter, Denny and the Destruction crew arrive at Doug's house shortly thereafter where they stage a home invasion in which they taunt, strip and severely beat and mutilate Jeanne before leaving her for dead.
Soon, the police intervene in the chase, which ends when Denny and Bitsy accidentally slide off the road at a curve and hit a telephone pole which the motorcycle explodes.
The final shot shows that Dexter has somehow escaped from the police and meeting with Lummox who gives him an update on Denny and Bitsy's deaths as well as several members of the crew in jail.
