Storyline: Two Americans sharing a flat in Paris, playwright Tom Chambers and painter George Curtis, fall for free-spirited Gilda Farrell. When she can't make up her mind which one of them she prefers, she proposes a 'gentleman's agreement': She will move in with them as a friend and critic of their work, but they will never have sex. But when Tom goes to London to supervise a production of one of his plays, leaving Gilda alone with George, how long will their gentleman's agreement last?
