The rich Collins family of Collinsport, Maine is tormented by strange occurrences.

The story of Dark Shadows begins with newly hired governess Victoria Winters arriving at Collinwood, the Collins' estate in Collinsport, Maine in search of her mysterious origins. She soon is caught up in the strange events and mysteries that seem to surround the Collins family. Eventually, the Collins' "cousin from England", Barnabas Collins, arrives and takes the show in a new direction; his vampire curse introduces a new history of the Collins family. Part of this revised history is the popular character of the witch Angelique whose jealously led to the tragic death of Barnabas' great love Josette and who placed the curse upon Barnabas.—Anonymous
