House of Dark Shadows

Willie Loomis, the Collins family handyman, is searching for old treasure in the family mausoleum when he accidentally frees Barnabas Collins, a 175-year-old vampire who enslaves him. Upon his release, he attacks Daphne Budd, secretary to Collinwood's matriarch, Elizabeth Collins Stoddard. She is discovered by Jeff Clark, who takes her back to the house where Dr. Julia Hoffman administers medical attention to her.
