In Love with Love(1924)

Ann Jordan, flirtatious and pampered daughter of a wealthy contractor, is engaged to Robert Metcalf, a relaxed and boring young man. She then meets Frank Oaks, who aggressively sweeps her off her feet, and she is presently engaged to him also. Mr. Jordan, Ann's father, becomes interested in one of Robert's friends, Jack Gardner, an engineer who is preparing a design for a bridge competition. The elder Jordan invites Jack to the house and covertly copies Jack's plans for the bridge.
