The Badge of Marshal Brennan

Jim Davis, later of DALLAS fame, is a gunslinger in this hokey back yard western who assumes the identity of a recently deceased federal marshall when he runs into a town being run by bad guys. He quickly straightens things out and proceeds to move on, but things keep happening to keep him in town. There actually is a plot: the only rancher of any consequence in the area has badly infected cattle, and will kill anyone who tries to interfere. The town doctor stands up to the rancher and Davis and the local sheriff back up the doctor. A young Lee Van Cleef is the ranch owner's sadistic son. The action is intermittent at best and poorly staged, the soundtrack would have better been left without music, and most of the cowboys are clean-shaven and neatly attired in that 1950s Roy Rogers style.
