Infamous Singapore smuggler Bully Brand possess a beautiful pearl necklace that is desired by Chinese merchant Chan Chang for his daughter Pain, a young white girl he had adopted. Warren Bradford, Brand's ward, returns from college and falls in love with Chang's daughter. When he finds out about the necklace that Chang wants, he persuades Brand to give it to him, and he presents it to Pain. However, Chang misinterprets Warren's gesture, which leads to a death threat against Brand--who Warren doesn't know is actually his father--if he doesn't marry Chang's daughter. Things go downhill from there.
