Shadows of the Sea: An idealistic sea captain, Dick Carson (Conway Tearle), is wounded by revenue officers while smuggling arms to a South American country. He finds aid and refuge at the home of Dr. Jordan (J. Barney Sherry) whose young wife, Dorothy (Doris Kenyon), is being courted by Andrews (Crauford Kent), who kills the doctor in a quarrel. To avoid the revenue officers, Carson takes them aboard his ship and sets sail for the Far East. He and Dorothy fall in love but, first, he must deal with a mutiny on his ship.
