Lucy volunteers for Ricky's Parisian apache dance number for an upcoming Tropicana show. And Ethel finds the perfect person to teach her the basic aspects of Apache dancing-Jean Valjean Raymand, who is the nephew of the woman who runs the French hand laundry. This Frenchman has more than dance lessons in mind, however. When Ricky finds him hiding in the hall closet, fireworks commence. Jean challenges him to a duel behind Radio City Music Hall, but they ultimately decide to stage a fake fight in the bedroom to teach Lucy a well-deserved lesson.
