Plot

Pat and Danny McGlone (both played by Jack Mulhall) are twin brothers raised by Mrs. Dean (Aggie Herring), a longtime family friend. Though inseparable in childhood, the brothers have grown into very different men. Pat, steady and honest, follows in their late father's footsteps and becomes a policeman. Danny, reckless and ambitious, falls in with a gang of criminals. Despite their opposing paths, both are in love with Mrs. Dean's daughter, Katie (Lila Lee). While Katie is torn between the two, Danny's flashy lifestyle—complete with a car and easy money—gives him the upper hand.
