Los Angeles family vacation is interrupted by nuclear war. Now they must escape into the mountains to avoid the radiation, the panic, and the rapists.

Despite the insipid nuclear holocaust effects (looks more like a thunderstorm), this is a surprisingly effective movie. Milland elicits effective performances from each and every member of his cast (Frankie Avalon has never been better). The menace, humiliation and sheer terror of rape has never been more poignantly depicted on the screen, and all without nudity. A minor classic.
