Sam, Trish, Beth, and Annie are four Valley Girls bored with shopping and frat parties. They come across kind Mr. Stanton, who is running a home for orphaned boys. Mr. Stanton and his charges are in danger of being evicted from their home if they don't come up with the rent money that is due, and one of the boys has taken to selling drugs for a couple of sleazy dealers. When Trish's prized "TUBUL R" Mercedes convertible is lost in a bet in which their Beverly Hills rivals have cheated, mayhem ensues as the Vals, with help from their frat-boy boyfriends, save Mr. Stanton and his boys from being evicted, give the drug-dealers their just deserts, and totally exact revenge on the Beverly Hills brats in a rematch.
