Tom Horn is a 1980 Western film about the legendary lawman, outlaw, and gunfighter. It starred Steve McQueen as the title character and was based on Horn's own writings. Tom Horn, a legendary frontier scout and tracker who helped to capture Geronimo, drifts around the quickly disappearing western frontier. The story begins as he rides into a small town and provokes prizefighter Jim Corbett, ending up in a livery stable, unconscious and badly bruised. Cattle company owner John Coble finds Horn in the livery and offers him his ranch to recuperate. He also offers him work investigating and deterring cattle rustlers who steal from the grazing association to which Coble belongs. He implies that the association will support Horn in implementing vigilante justice. Horn accepts the offer and receives the approval of U.S. marshal Joe Belle at an association picnic where he also catches the eye of the local schoolteacher, Glendolene.
