Myra, a shy and sensitive young woman, loses her virginity to a rapist on her wedding night. Afraid to tell her husband, Mark, she grows to fear all sexual contact. On an island vacation they meet Bob, an artist who has been forced into marriage with Helen, a nymphomaniac. Myra and Bob are drawn together because of their unhappy sexual experiences while Mark, sex-starved, finds release with the insatiable Helen. Helen arranges an orgy and, to distract Myra from Bob, introduces Myra to Corrina, a lesbian. Meanwhile, Mark meets Ilsa and is invited to her cottage; and Bob, hoping to persuade Myra to go away with him, tells her that Mark is unfaithful. Myra turns instead to Corrina for comfort. The two women die tragically in a fire, and Mark comes to his senses and sets out to find true happiness with Ilsa. Bob leaves Helen, and he remains alone and disconsolate after Myra's death.
