Showdown at Diablo

A gang of hired killers rides into Diablo. Lofty believes that they're in town to murder a state senator with powerful enemies in the capitol. When Lofty discovers that the gang's leader once rescued him from certain death during their days in the U.S. Cavalry, he is reluctant to take him on and possibly kill him in a shoot-out. As a result, the townspeople force Lofty to resign.
