The Charming Mrs. Chase (1920)

Jimmie Wickett's marital life becomes monotonous. At a dinner one evening he becomes infatuated with the charming Mrs. Chase. He invites her to lunch on the following day. Both are to keep the engagement a secret. Jimmie comes to the breakfast table the next morning dressed as a dapper youth. Mrs. Wickett, suspecting, comments laughingly on the effect that Mrs. Chase has had on her husband. Jimmie admits that he is taking Mrs. Chase to luncheon. Fine, says Mrs. Wickett. Mrs. Chase is late with her appointment. The luncheon develops into a boresome affair. Both return to their respective households contented with their respective mates.
