Bastard, Go and Kill 1971

The young Mexican peon Chako, George Eastman, is hunted and nearly hanged by a band of Americans after the seduction of Susanna, Scilla Gabel. He manages to slip away and return to Mexico, where a seasoned bounty hunter named Slim trails him, determined to collect the reward. Although Slim closes in and captures Chako, the quick-witted young man outsmarts him, leaving the hunter stranded in the desert.

Chako arrives in San Rosario, where he is welcomed as a hero by many, though not everyone shares that view. The jealous Asuncion, Antonella Steni, sees the situation differently and has Chako thrown into prison. A corrupt local official, taking a higher payoff from the visiting American, further twists the fates of everyone involved, intensifying the pressure on the town.

Meanwhile, the powerful landowner Don Felipe Antonio de Martinez, Furio Meniconi, faces trouble when two men block access to his shops. He tasks the loyal henchman Sanchez, Franco Lantieri, with doing the dirty work and then blaming Chako for the crimes. The injustice sticks, and Chako winds up back behind bars, fueling a deeper conflict in the community.

A big party and the ensuing chaos give Slim a chance to move. He frees Chako and aims to preempt the murder gang led by Cherokee, a hired killer played by José Manuel Martín. The two men—one a hunter, one a fugitive—form an uneasy alliance and begin to dismantle the web of scheming around them.

In the climax, Slim and Chako work together to shut down Sanchez, who has already murdered Don Felipe. Order starts to return to the area as justice edges closer. Slim hands Sanchez over to the authorities, and Chako is brought to Asuncion, setting the stage for a resolution that seeks peace after a long, tense struggle.
