This dramatic adventure finds the flirtatious Cherry O'Day (Betty Compson) as the daughter of the Shanghai saloon keeper Terrence (Spottiswood Aitken). She works in the dive and entertains the patrons, sending them away after they cease to amuse her. Cherry falls for Gordon Deane (Milton Sills), the American writer and adventurer who barely notices her. When her father dies, she marries banker William Blaine (Joseph Kilgore). MacGregor (Mitchell Lewis) is the unrefined sailor who vows to return from a year at sea to marry the disinterested Cherry. The marriage crumbles, and Cherry is shipwrecked on an island with a lighthouse where she meets Gordon, MacGregor, and a financially ruined young man. The young man and MacGregor engage in a fierce battle over Cherry on the deck of the lighthouse high above the jagged rocks below. She watches in horror as the rail breaks and both men fall to their deaths.
