Handyman Willie Loomis accidentally releases vampire Barnabas Collins from his chained coffin. Barnabas introduces himself to the Collins family as a distant relative from England and begins to romance beautiful new governess Victoria Winters. The town of Collinsport is soon terrorized by a series of deadly attacks.
The mysterious child ghost of Sarah Collins appears to Victoria Winters, and leads her to a library in Collinwood's closed-off west wing, and gives her an old diary. Barnabas and his servant, Willie Loomis, are stunned when the evil apparition of the witch Angelique materializes from the fire in the fireplace.
