Giallo - The Killer Must Kill Again

In Torino, American model Celine is abducted by a taxi driver while on her way home to meet her sister Linda at her apartment. The next morning, Linda reports that Celine is missing and the sergeant in charge directs her to FBI agent Inspector Enzo Avolfi 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 a nearby fountain, she tells Enzo and Linda that the abductor's skin is yellow in color, and Linda concludes that he has jaundice. They go to the Policlinic di Torino to find the killer.
