Los ríos de color púrpura

In Guernon, an isolated mountain area where the local University rules the town, the Chief Inspector Pierre Niemans (Jean Reno) arrives from Paris to investigate a hideous crime, when the victim was tortured and mutilated before dying. Meanwhile, Detective Max Kerkerian (Vincent Cassel) comes to the same place, following the investigation of a profaned tomb of a young girl. They join forces and find a plot of eugenics in the University, with abductions, murders and revenge.

Yesterday I saw this great movie again, trying to find some answers to questions I raised the first time I saw it four years ago. Unfortunately, they have no explanations along the story. "Les Rivières Pourpres" has magnificent locations, maybe the most beautiful landscapes I have seen in a crime movie. The cast is outstanding, highlighting the charismatic Jean Reno and Vincent Cassel. However, the screenplay has flaws and presents a deceptive conclusion. My questions are: (1) If Judith was kidnapped in the nursery of the hospital, exchanged by the daughter of another person, what happened to the other child? (2) Who raised Judith, if her mother got crazy and went to a dark cell in a convent? (3) If her mother knew where her other daughter was, why didn't she go to the French justice and fight to retrieve the child? (4) How Judith found and approached Fanny? Anyway, usually worths watching serial killer stories and this one is very above the average. My vote is eight.

Title (Brazil): "Rio Vermelhos" ("Red Rivers")
