Broncho marries a Mexican girl at the earnest entreaty of her dying father. Later a Mexican singer wins her love and, to get Broncho out of the way, she has him arrested and jailed on the charge of having assaulted her. In a frenzy of rage, Broncho secures the sheriff's revolver, escapes from jail and tracks the pair at his shack. Meanwhile the Mexican singer's sweetheart, jealous of his attentions to Broncho's wife, reaches the shack first and, when Broncho bursts in, gun in hand, he finds the pair dead on the floor, her knife having found both their false hearts.
