Paul and three other punks, Arnie, Vince and Dirk, are admiring a parked sports car and intending to take it for a joy ride, when they are surprised by its owner, Miles who orders them away and is met with a barrage of filthy names. A few nights later they break into Miles' garage and he catches them and threatens to call the police. Paul tells him they want the car for a ride and they will have it sooner or later. The young hoods then launch a campaign of terror against Miles and his wife. Paul realizes he has more pleasure in frightening Miles than in trying to get the car, and one day they force their way into the Miles home and brutally attack Mrs. Miles after she refuses to produce the car keys. Now thinking that Miles is in his power, Paul meets him to take delivery of the car. When Paul steps into the car, Miles pulls a gun and orders him to drive out of town at a breakneck speed.
