1 hr. 14 min.
Neil Glynn (Dennis Weaver) ; his wife, Arlene (Estelle Parsons) ; and their teenage children, Steve (Kristoffer Tabori) and DeeDee (Susan Dey), are all packed into the camping van for an off-season family vacation at the beach. When they run afoul of some threatening, dune buggy-driving hippies en route, they little suspect what's in store for them over the course of the weekend. The hippies follow them, and variously bully, intimidate and terrify the Glynns until Neil decides he's had enough.
