As described in a review in a film magazine,[3] big Bill Branigan (MacDonald) leaves his sweetheart Bessie (Miller) for Curlytop (Mason), whose unconscious beauty naiveté enthrall him. Shanghai Dan (Oland), who dominates a gang of Chinese crooks in the Chinatown centered on Limehouse in the East End of London, also desires her. Determined to reform, Bill sets out in search of a job, so Bessie revenges herself by getting Curlytop drunk and cutting off her golden curls. Bill returns but cannot find Curlytop, and is persuaded to rekindle his relationship with Bessie. After he finds the golden curls among her belongings, Bill forces Bessie to reveal the whereabouts of Curlytop. Curlytop has been working for Shanghai Dan as a waitress on a floating barge. As Dan is hypnotizing her, another vessel crashes into the barge. Dan is drowned while Curlytop is rescued by Bill.
