The overweight debutante daughter of the world's wealthiest couple falls in with a gang of tripped out, skydiving pseudo-reactionary pop stars, who take their beliefs of the American ideal to profoundly impossible heights.

Eighteen-year-old Tara Nicole Steele, overweight and insecure, returns home to her wealthy parents in California after having been away for years at a Swiss boarding school. Her homosexual father, Willy, is an airplane manufacturer. Her mother, Astrid, is a former star of stag films and a status seeker who has a passion for jewels. Not quite sure what to do with Tara, her only child, Astrid plans a coming out party for the girl. The extravaganza is actually a showcase for Astrid's jewelry; and Tara, unnoticed, leaves the party and is nearly run over by Bogart, a pop singer who was invited to the affair to perform with his group, Joe, Anna Livia, and Santoro. Bogart invites Tara to go for a ride with him; she accepts and they immediately have sex. Tara's absence eventually begins to worry her parents, and they are about to call the police when Tara returns with Bogart and his group. Bogart announces that he would like to marry Tara, but Tara's initial wonderment turns to bewilderment when Bogart begins to flirt with her mother. Bogart soon embarks on an affair with Astrid, who after much teasing agrees to go skydiving with her future son-in-law and his friends. Tara pilots the plane, and Willy watches from the ground as the group jumps. Once they have all jumped, Bogart and his friends taunt Astrid by passing between them her diamond necklace. All land safely but Astrid, who plunges to her death after her parachute fails to open. Tara returns home and finds her father slain. It is revealed that Bogart had been involved in a homosexual liaison with Willy, and he killed both Astrid and Willy. Unable to accept reality, Tara goes insane.
