A young woman enrolls in a Salem girls' school to investigate the mysterious circumstances surrounding her sister's suicide and uncovers a fiendish plot involving the devil himself. Predating Dario Argento's "Suspiria" by several years, this made for television thriller benefits from a strong lead performance by Pamela Franklin and some genuinely creepy atmosphere. Remade again for television in 2000 with Kate Jackson, who played a student in the original, now playing the part of the headmistress.
