Franco Arno (Karl Malden) is a blind retired journalist who overhears a suspicious conversation preceding a murder. He then gets involved with Carlo Giordani (James Franciscus) a newspaper reporter and together they try to solve the mystery. Seems a pharmaseudical company is trying to conceal a huge research secret. With each clue they uncover their lives become more and more endangered. Everytime they find someone who could lead them to the truth that person winds up dead. Attempts are made on both of their lives. It becomes a race against time to uncover the murderer before they are killed.
A complex tale of intrigue, murder and big hair. I have to say this was not one of my favorite Argento flicks. It was rather draggy at times and didn't seem to really have any of his flare with color & light. It was almost like he was trying to be more like Hitchcock with this one. Not a bad story and was worth the watch but really not a fair demontration of his directing talents.
