As described in a film magazine review,[3] Margot Le Blanc, left a small fortune by her foster mother, goes to Monte Carlo and loses it all gambling. When she is falling into the hands of a scheming thief, she meets Hugh Kildair, an artist that lives in the same house. After hearing her story, he suggests that she become his housekeeper under an arrangement where they shall live together as brother and sister, to which she agrees. Later, Hugh falls into a trap set by a gang of thieves involving their accomplice Mrs. Belmire. The aim of the gang is to force Hugh to reveal a cipher system entrusted to him by old Professor Durand. The plans of the gang are foiled by the arrival of the police. This experience has opened Hugh's eyes to the fact that he loves Margot, who has loved him all along. They are married without delay and return home this time as husband and wife.
