The murder of Dave Lockheart's wife by a set of desperados who plague the Red River country of Texas leads him to a desperate mission for revenge. Though he was once a soldier, Lockheart is no natural killer, but his quest for revenge becomes marked by murder, bullets, and gun-smoke, and brings him face to face with deadly men. Then he meets Helen, who must overcome difficulties that few women ever face. Now she must teach Lockhart that there can be a world of difference between vengeance and justice.
