Trust Your Wife (1921)

Margot Hastings, the lovely wife of a handsome but needy inventor, Dick, is the latest prey of Lothario financier, Slater T. Holcomb who may be persuaded to produce some of her husband's inventions. Holcomb promises Margot jewels and riches if she will be agreeable. She manages to keep her distance until he invites her aboard his yacht, where she makes him realize how contemptible she regards his behavior. Claire Bodai, the financier's girl, jealous of the young wife, goes to Dick, informing him that his wife has been unfaithful. But the contrite financier reassures Dick that his wife not only is faithful but has made him, Holcomb, see the foolishness of his ways. Dick then receives financial backing.
