A successful dentist has for years being hooking women by pretending to be married. He now meets a sweet young thing, and his usual 'pretending to be married' game falls apart with her. The upshot is that he, her, and his dental nurse and her two kids go to Hawaii for a holiday where they enjoy the sun while he tries to maintain the charade. Naturally he finds himself falling for his nurse instead of the hottie he thought he was in love with.
