John Preston, ranch owner, owes a large sum of money to Don Jose Praz. The Don's rascal son, Raphael, with the aid of an accomplice, steals some of Preston's cattle. Raphael loves Kate Preston and urges his father to press the matter of the notes as a lever to win Preston's consent to the marriage. Kate's heart, however, belongs to the foreman, Jack Deering. Unable to force Preston's consent, Raphael kidnaps the girl and carries her to a lone cabin. Game as every Western girl who has ridden the free plains, Kate fights him, but the villain's strength beats her down. The girl's horse has meanwhile run home. Jack, accompanied by the cowboys, starts on the trail. He arrives at the cabin and, after a death duel with the Mexican, kills him as the cowboys come up.
