Dario Argento
A jazz pianist and a wisecracking journalist are pulled into a complex web of mystery after the former witnesses the brutal murder of a psychic.
A psychic who can read minds picks up the thoughts of a murderer in the audience and soon becomes a victim. An English pianist gets involved in solving the murders, but finds many of his avenues of inquiry cut off by new murders, and he begins to wonder how the murderer can track his movements so closely.
