Tom Milford, foreman of the Hayden ranch, and Sylvia Hayden, daughter of the ranch owner, are in love. Hayden has been notified that Archie Hollister, son of an old friend in the east, is coming to visit the ranch. Just before Hollister arrives, a cowboy brings word to the ranch that Simms, a troublesome neighbor, has been illegally interfering with the ranch supply of water.
