The Ranchman's Vengeance
Lorenz Pedro, a Mexican half-breed, owns a small sheep ranch, and lives happily with his wife Marie and little daughter Lois. One exceedingly hot afternoon, Tom Flint, riding across the ranch looking for work is overcome by the heat, and Pedro, acting the part of a good Samaritan, takes him to his home, where Marie, through careful nursing, soon has him quite himself again. Pedro is out daily with his flock, leaving Marie and Flint together, offering an opportunity which Flint ungratefully takes advantage of, resulting in his completely winning Marie's love. Manuelito, Marie's father, is suspicious and comes upon them while Flint is declaring his love.
