Dark Shadows - Season 5 Episode 33 : DS-400 1971

Reverand Trask performs the rite of exorcisim at the threshold of the Old House. According to Trask, the witch should run out of the house during the exorcism. Angelique casts a spell that creates the illusion of a fire in Victoria's room. While she is casting the spell, Barnabas overhears her. The spell makes Victoria run out of the house screaming 'FIRE' and into the arms of Trask. Trask kidnaps her without telling Barnabas or Angelique. Barnabas now suspects that someone in the house is a witch, but he does not know if it is either Victoria or Angelique.
