Jimmy Berry, junior partner in a flourishing business firm, is engaged to Betty Carson. He is taken into confidence by Dorothy Dawson, his partner's wife, who secretly plans to open a business branch in South America. Their secret meetings generate gossip, and Dawson, who is insanely jealous, threatens divorce, while Betty's uncle forbids her to see Berry. Dawson compels Berry to go to South America with him, and the appearance of Dorothy there leads to further complications. When Berry attempts to depart, he is captured and returned, with Dorothy, to the home of Gardez, an importer, who arranges a duel between Berry and Dawson. Dawson is wounded, and again Berry takes French leave, via motor car, but is kidnapped by an outlaw known as El Pavor. After numerous other complications, Berry escapes from South America and returns home in time to prevent Betty's marriage to another man.
