Simon Valjon is inordinately jealous of his pretty, young wife, Mary, who, however, never gives him cause to doubt her fidelity and affection. The young couple have their home on a South African ranch in a neighborhood infested by wild beasts, particularly lions. Kimball, an artist, seeks their hospitality. On the following morning Kimball makes a sketch of the ranch house, and when Mary comes to the door he tells her to remain there while he sketches her in the picture. He arranges her pose to make the picture more effective. Simon observes this and misconstrues his motive. Later on, Kimball catches Mary when she falls from a stool while placing his sketch on the wall, and Simon sees this action and misconstrues it also. A predatory lion enters the house in the absence of the men folks, who hear Mary’s screams for help. Kimball offers himself as a bait to lure the lion from the house through an open window, and Simon and his Uncle Paul lasso the brute, thereby saving Mary from death. Simon apologizes to the hero for his jealousy.
