Synopsis
Sophisticated and cultured aristocrat Yvonne Montford, while somewhat philosophical about the many loves of her philandering husband Philip, is also somewhat bitter about them. Yvonne finally outwits her husband just as he's about to leave for Biarritz with chorus girl Lulu. Finding the tickets in his pocket, Philip tells her they were meant for her, and he will be joining her in a few days. She heads for Biarritz, and philandering Phillip gives the other ticket to Jean Corot, a writer who is quiet and trustworthy. But on the train and at the resort, Yvonne and Jean are constantly thrown together, and when philandering Philip arrives a few days later, Yvonne and Jean are very much in love with each other. Philip offers Yvonne a divorce, which she accepts, and she and Jean are married. But La Belle Toulaize, a Parisian actress and vamp-first-class, shows up to ensure that the marriage ceremony doesn't provide the 'Finis.'
