Journey's End (1918)

When Aline Marsden learns that her husband Phil has been flirting with musical-comedy actress Bernice De Armond, she and her uncle, Pop Moore, compel him to sign a contract that gives each of them complete marital freedom for three months. Aline then travels to Palm Beach, Florida, accompanied by Pop and her sister, Jess Alden, while Phil remains in the North with Bernice. In Florida, Aline engages in a flirtation with Phil's old college friend, Wayne Annis, and when her husband, now weary of Bernice, comes to Florida, she gives him a chilly reception. Wayne, who has fallen in love with Jess, agrees to help Pop effect the married couple's reconciliation by arousing Phil's jealousy. The plan works so well, however, that the enraged husband nearly shoots his old friend. In the end, the friendship is preserved, Aline and Phil are reunited, and Wayne professes his love for Jess.
