A year after her husband Bill has been reported drowned in a boating accident, Vicky Cardew marries his business partner and best friend, Henry Lowndes. As Bill's name is being removed from the office doors, Vicky's father George receives a long distance call from Bill, and is shocked to learn that he is alive. Bill tells his father-in-law that he will be arriving in town that night by airplane. For the past year, Bill has been marooned on a desert island and is now eager to return home to his wife. Vicky and Henry go to the airport to meet Bill, but neither one can summon the nerve to tell him what has happened. As Bill makes plans to spend his first night with his wife, they finally tell him the truth. Trouble begins when both husbands begin lavishing love and attention on their mutual wife, who refuses to decide between them and instead embarks upon a dizzying flirtation to keep them both on equal terms. Though tempers begin to flare, Vicky enjoys the attention and competition between her husbands. As she mulls over her dilemma, the two men put on a show of strength for her, each trying to outperform the other by jumping over living room furniture, until both men suffer injuries. When the husbands become pals for a night and walk out on Vicky to teach her a lesson, she calls the police. The police investigators nab her husbands, but Vicky is unable to conceal her illegal living arrangement from the police and is hauled off to court. Although a judge decides that Bill is Vicky's legal husband, Henry refuses to admit defeat and continues to court her. Both men ignore the court ruling and vow to keep Vicky happy in the future and share a dance with her to show the sincerity of their intentions.
