When We Were 21

Dick Audaine, known affectionately as the "Imp," is engaged to Phyllis Ericson, even though she is in love with his guardian, Richard Carewe. Meanwhile, the Imp has fallen in love with Kara Glynesk, who is only interested in his money. Phyllis intercepts a love letter from Kara and erroneously believes it is intended for Richard. In an attempt to protect the Imp, Richard hides the truth from Phyllis. Richard and the "Trinity," three life-long friends and self-appointed co-guardians of the Imp, try in vain to stop his marriage to Kara. However, Kara quickly discovers that her husband is penniless and finds a new lover. The Imp realizes his folly, and Phyllis is now free to marry Richard.
