One of Roman Polanski's lesser-known films, Diary of Forbidden Dreams (also known as What?) stars Sydne Rome as an attractive young hitchhiker who, as the film opens, accepts a ride from three men in a car, who later attempt to rape her. She escapes their clutches and makes her way to a mansion owned by millionaire Joseph Noblart (Hugh Griffith), who is overseeing a decadent party. Among the guests at his home are a pair of table-tennis players, a man with a harpoon (played by Polanski himself), and a hedonistic pimp played by Marcello Mastroianni. The woman's sexually charged adventure is an homage to Alice in Wonderland.
