Rustling

When cattle thieves outside of Laredo, Texas, shoot down U.S. Deputy Marshal Harold Gosling and his posse, Marshal Frank Bass is called upon to investigate the killings and return the small herd of cattle to their rightful owner, The King Ranch in Southeastern Texas. The cattle are a result of a breeding experiment that has been several years in the making. Along the way, Bass encounters conspiracy, treachery, and murder, as well as a villain from his recent past intent on killing Bass, the man who had crippled him in a shootout.
