Synopsis:
William Peter Blatty, author of The Exorcist, directed this intriguing, deliberately-paced thriller based on his novel Legion. Ignoring the events of John Boorman's disappointing Exorcist II: The Heretic (1977), the film moves ahead 15 years from the end of the original, when Georgetown is being plagued by occult murders bearing signs of the long-dead Gemini Killer, James Venamon (Brad Dourif)
