Rose Boland, a pretty young ranch owner, quarrels with her foreman because she dislikes his attentions. She discharges him from her employ, and her cowboys eject him from the ranch. The disgruntled foreman proceeds to join a band of cattle rustlers and engages with them in the looting of cattle. One day while Rose is making a tour of inspection on horseback, the rustlers, who have been lying in wait, make her a prisoner. They bind and gag her, and lock her up in an isolated cabin. The boys of the ranch go in search of her and notify the sheriff that she has disappeared. The sheriff has cast eyes at Rose in the past and is all eagerness to find her. Alone, he rides up to the deserted cabin, having trailed her by a handkerchief which she cleverly dropped in the pathway, as a clue. The rustlers wound him when he tries to make prisoners of them, and they escape temporarily. The cowboys ride up, release Rose, and she nurses the sheriff back to life and strength. The rustlers are dealt with according to the traditions of western law. The sheriff gets his reward by making a prisoner of Rose's heart.
