 An unruly teenage gang, led by Mark Damon, gets their kicks by crashing square teen parties around town. At an innocent teen gathering, Damon charms rich spoiled brat Connie Stevens into accompanying him to a swanky motel party and she drags along her decent young date (ex-child star Bobby Driscoll). There, they run into Driscoll s alcoholic mother ( 30s bad-girl Frances Farmer), who falls down a flight of stairs while being escorted out. Along the way, we get to know the kids  parents which provide us with an insight as to their children s troubled lives. Both Farmer and Driscoll s last movie.
