Infierno de cobardes (1973) DVD9

The sleepy Wild West mining town of Lago, named after a local lake, is shaken up when a tough stranger (Clint Eastwood) stands up to the local gun champions and kills them in an uneven duel. The locals are impressed, enough to vote in town council to let Sheriff Sam Shaw (Walter Barnes) explain those were hired guns overstepping their task. But the three worst the town ever saw, which they were hired to check, are being released from jail. The Stranger accepts seemingly reluctantly, to be put in charge of order and mounting a defense, recruiting the factotum dwarf as his Deputy. Instead of doing their dirty work, he abuses his "blank pay check" not just for free goods, but also to commandeer everyone in a militia and transform the whole town. The jail-freed trio realizes too late that he's after vengeance for the whip-torment they inflicted on weakling Marshal Jim Duncan (Buddy Van Horn) years ago, still the stranger's daily nightmare.
