The Virginian (1929)

Molly Wood arrives in a small western town to be the new schoolmarm. The Virginian, foreman on a local ranch, and Steve, his best friend, soon become rivals for her affection. Steve falls in with bad guys led by Trampas, and the Virginian catches him cattle-rustling. As foreman, he must give the order to hang his friend. Trampas gets away, but returns in time for the obligatory climactic shootout in the streets.
