Patience Winslow is an impulsive heiress who marries a much-older man whom she really doesn't love. While honeymooning on her yacht without her new husband, Patience is marooned on a desert island with handsome Captain Edmunds. Her head full of notions that she's gleaned from radio dramas and pulp novels, Patience demands that she and Edmunds enter into an in-name-only marriage, observing the responsibilities and proprieties of matrimony without the sexual entanglements. Complications naturally arise.
