A killer disembodied hand stalks the feuding heirs of a late musician in this cult horror classic, featuring Peter Lorre and J. Carroll Naish.
Our story beings in the charming Italian city of San Stefano, home of Francis Ingram (Victor Francen), a renowned concert pianist who was partially paralyzed by a stroke and can only play the piano with his left hand. He lives a secluded with life in a typical horror movie mansion with his nurse Julie Holden (Andrea King), his secretary Hillary Cummins (Peter Lorrre), and Bruce Conrad (Robert Alda), a talented musician who I think transcribed music that Ingram could play. Ingram credits his perseverance and will to continue playing to Julie, possibly being in love with her. Hillary's thrilled about this, as every moment Julie keeps Ingram occupied is another moment Hillary has free to read the numerous books on astrology and the occult in Ingram's library - so he's naturally freaked at the thought of Julie leaving Ingram's service with Conrad. One night, while dining with all of them and his lawyer Duprex (David Hoffman), Ingram announces he's made up his will and asks them all to sign it as witnesses.
