In Manhattan, dentist Julian Winston works with his efficient nurse/receptionist Stephanie Dickinson, whom he compares to a cactus flower because she represses her emotions. He spends the first anniversary of his affair with 21-year-old Toni Simmons on a date with an Australian air-hostess. Believing that Julian is married with three children and chose to spend the evening with his family, she attempts suicide, but her next-door neighbor, young aspiring writer Igor Sullivan saves her life. When Julian learns what Toni did, he decides to marry her. Toni does not want to be a homewrecker and asks to talk to Mrs. Winston to be sure that she wants the divorce. Julian does not want her to know that he is a liar, so he asks Stephanie to pose as Mrs. Winston.—Claudio Carvalho, Rio de Janeiro, Brazil
