It was made into a film in 1929, directed by Edward H. Griffith and starring Ann Harding and Fredric March.

[1][2][3] Jim Hutton and Mary Archer are liberal-minded lovers content to remain faithful to each other in spirit only without need of a marriage certificate.

Among the wedding guests is the young composer Richard Parrish, hardly disguising his admiration for the bride, and Noel Farley, whose passion is exceeded only by the pain of losing Jim to another woman.

When Jim unexpectedly returns, he tells Mary of his affair with a French woman.

In the end their mutual love is confirmed, and they decide to adopt traditional marriage morals and remain monogamous.
