Man in the Shadow (movie, 1957)

In effect, modern cow town Spurline is run by Virgil Renchler, owner of the Golden Empire Ranch. One night, two of Virgil's henchmen go a little too far and beat a "bracero" ranch hand to death. Faced with an obvious cover-up and opposition on every hand, sheriff Ben Sadler is goaded into investigating. His unlikely ally: Renchler's lovely, self-willed and overprotected daughter. Will Ben survive Renchler's wrath?
