一个人格分裂的妹子Florence和闺蜜一起看露天电影的时候,遭遇了一起凶杀案。 没过几天,她受到朋友的邀请,去海滩度假。在这次party上,又接连发生了好几次凶杀案,而且每次她都精神分裂成一个叫Ann Bowman的彪悍女。Spoof of 1960's Beach Party/Gidget surfing movies mixed with slasher horror films stars Lauren Ambrose as Florence Forrest, a not-so-innocent girl in 1960's Malibu who becomes "Chicklet" the first girl surfer at Malibu Beach, only Florence suffers from dissociative identity disorder and occasionally her alter ego Ann Bowman, a sexually aggressive, foul-speaking girl, comes out in which during that time several beach goers are found murdered. The suspects include Chicklet herself, surfer Kanaka, B-horror film actress Bettina Barnes, exchange student Lars, and even Chicklet's own mother.
