I Saw That Movie Years Ago. I Think This Lady Is A Vampire Or Some Sort Of Monster And A Girl Or Boy In The Family Play A Violin And It Hurts The Lady's Ears. Also She Hides The Wife Of The Family And Tries To Become The New Wife Of The Guy. Something Like That. In The End They Find The Wife In Like Some Spider Web Or Something Inside Of A Cave. Does Anyone Know Or Have A Clue. Please And Thanks.
