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. Ann falls in love with Jack, who is eligible and seemingly indifferent; Jack is too modest to declare his love, so Ann is forced to propose to him, and Jack accepts. Jack's plan for the bridge wins the competition, but in Jordan's name rather than his own. Jack breaks off with Ann, believing that she has professed love for him only to help her father steal his plans. Jack and Ann are reconciled, however, when her father explains that he prevented Jack from winning the competition only to be sure that Jack was free to accept an extremely important position with the Jordan firm.
