Butcher's wife
In Torino, Celine, an American model, is abducted by a taxi driver while en route home to meet her sister Linda, visiting at her apartment. The next morning, Linda reports that Celine is missing - the sergeant in charge directs her to F.B.I. agent Inspector Enzo Avolfi. He's from the Special New York City Department investigating a serial-killer that kidnaps foreigners to destroy their beauty. When a Japanese woman is found at nearby a fountain, Enzo and Linda find that the girl is calling the abductor's skin is "Yellow" in color and Linda concludes that the guy might have jaundice. They go to the Policlinic di Torino to find the killer.
Doctor
In 1990, as a boy, Giulio was chased through the woods by two women after spying on them practicing witchcraft. Now a young film student in Turin, he watches his neighbors in the flats across from his third floor apartment, especially Sasha when she's naked or arguing with her mother. Giulio's girlfriend is disgusted with his voyeurism, but, after a murder occurs, Giulio is convinced that two relative strangers, just as in Hitchcock and Highsmith's "Strangers in a Train," have agreed to murder each other's bête noir. He follows his suspects, ends up with an intruder and a broken foot, and may be in real danger. Is he more than a peeping Tom?
