This takes place at the all girls Helen Page School in Salem, Massachussetts, run by a headmistress with a dark secret (played by the wonderful Hackett).

Things are mysteriously being set on fire (including some of the students!) when an uninvited priest-turned-exorcist (Farentino) appears with a mission.

A good cast, including P.J. Soles, Dinah Manoff, and Ann Dusenberry in minor roles, a terrific setting, and a brisk showdown/conclusion...make this one worth seeing.

Filmed at Reed College in Portland, Oregon.
