Elli and Marco are an unquestionably unusual wedded couple. Due to a damage as a kid, Marco harbors homosexual drives that he represses inside his married life and Elli is a barely surpressed nymphomaniac. The marriage is useful for both of them as it allows them to blend in within the confines of their regular social life in a sanctimonious provincial town. But then a strange woman bursts into their world and Marco's deviant behavior come to light again but now he has a thirst for murder.

Hernandez, the sheriff of a small Mexican village, joins a group of townsmen with the intention of killing young orphan Manuel and robbing him of his inheritance. Killer Luke, now an alcoholic for having murdered his own son by mistake, who is chosen for the task, instead decides to take the defence of the poor child.
