The best Juan López Moctezuma’s movies

Cristina Carver (Angelica Maria) finds herself in dire straits after she arrives to spend some time with her TV-reporter husband (Dean Stockwell) who is visiting a Latin American country run by a military dictator. After a car accident one day, Cristina brings the helpful Col. Kostik (Donald Pleasence) home and then kills him in self-defense when he violently attempts to rape and murder her. Terrified, she covers up her act and hides the body, yet in spite of her husband's efforts to protect her, a local police detective starts to figure out what really happened.

A young man kidnaps a woman and embarks on an energetic crime spree. The reason for his behavior gradually becomes apparent.

The story unfolds in an underclass neighborhood of Mexico City, a place where a unique troupe features a circus act, led by Don Ramón (López Moctezuma himself.) He and his wife Petra (Isaura Espinosa) have to take care of the daughter of a neighbor who has been jailed for drug trafficking. Petra decides that the girl (who is only 5 years old) must earn a living, entrusting her several domestic tasks; the little girl, which he nicknamed "Flea" befriends Pepito, who works as a clown on the street. Things get complicated when somone with satanic tendencies arrives to Ramon's house, and the visitor develops an interest on Petra. A fight between the three adults causes that "lil Flea" suffers a fatal accident, so the solution will be to use her meat for the tamales sold by Petra.
