Gidget, Frankie and Annette beach party epics, and Hitchcock psychological suspense thrillers such as Spellbound and Marnie are given a shotgun marriage. Chicklet Forrest, a teenage tomboy, desperately wants to be part of the surf crowd on Malibu Beach in 1962. One thing getting in her way is her unfortunate tendency towards split personalities. Among them is a black check out girl, an elderly radio talk show hostess, a male model named Steve and the accounting firm of Edelman and Edelman. Her most dangerous alter ego is a sexually voracious vixen named Ann Bowman who has nothing less than world domination on her mind.
