Less Than Kin (1918)

Lewis Vickers accidentally kills a man and goes to Central America. Here he meets Robert Lee, who bears a remarkable resemblance to him. Lee is a worthless young chap whose father is anxious to have him return to the United States. On his death bed Lee turns his papers over to Vickers and begs him to assume his name. Arriving in New York, Vickers goes to the Lee home as Robert Lee, and discovers that the dead man has willed him a badly blotted past that includes a wife and two children and a large collection of debts. He also finds a beautiful adopted daughter in the Lee household and promptly falls in love with her. The only way he can stand any chance of winning the girl is by telling the truth about himself.
