Dark Shadows Collection 22 (DVD)

In the year 1995, Barnabas and Dr. Julia Hoffman wonder what has happened to the Collins family when they find the Collinwood estate abandoned and in ruins. They learn that both Carolyn Stoddard and Quentin Collins have gone insane. Barnabas witnesses the ghost of Gerard Stiles and realizes that Julia is under the spirit's power. In 1970, the ghost of Daphne Harridge, a nineteenth century governess, appears to Quentin, who locates her diary in the west wing.
Barnabas is stunned when he meets astrologist Sebastian Shaw's assistant, Roxanne Drew, who is identical to the Roxanne that Barnabas knew in parallel time. When Julia discovers fang marks on Maggie Evans' neck, Barnabas assures her that he is not responsible and vows to find the vampire who attacked Maggie. David Collins and Hallie Stokes become possessed by the spirits of Tad Collins and Carrie Collins from 1840.
