In Los Angeles' raging skateboarding scene of the mid-1980s, Corey Webster (Josh Brolin), the preppie ringleader of a skateboarding dynasty, falls in love with the sister (Pamela Gidley) of Tommy Hook (Robert Rusler), the punk leader of a rival gang. The forbidden romance flowers as the two gangs train for a grueling, 20-mile, downhill race -- with corporate sponsorship as the reward for whichever team can thrash its way to victory.
