On the last day of summer vacation in 1962, friends Curt, Steve, Terry and John cruise the streets of small-town California while a mysterious disc jockey spins classic rock 'n' roll tunes. It's the last night before their grown-up lives begin, and Steve's high-school sweetheart, a hot-to-trot blonde, a bratty adolescent and a disappearing angel in a Thunderbird provide all the excitement they can handle.
