When vigilante land baron David Braxton hangs one of the best friends of cattle rustler Tom Logan, Logan's gang decides to get even by purchasing a small farm next to Braxton's ranch. From there the rustlers begin stealing horses, using the farm as a front for their operation. Determined to stop the thefts at any cost, Braxton retains the services of eccentric sharpshooter Robert E. Lee Clayton, who begins ruthlessly taking down Logan's gang.
Unfortunately the movie The Missouri Breaks is not yet available on HBO Max.
