Has nothing to do with the Jamie Lee Curtis 1980 original. Here in 1957 a cheating Mary Lou Maloney (Lisa Schrage) is named Prom Queen. She is burned to death after a prank goes horribly wrong coming from a jilted lover. Fast forward 30 years and her spirit is walking the hallways of Hamilton High. Or rather possessing Vicki Carpenter (Wendy Lyon) who is dating the son of Bill Nordham (Michael Ironside) who was hurt by Mary Lou 30 years prior on prom night. Does quite a good job on the possession angle and sort of feels almost like a Canadian-NIGHTMARE ON ELM STREET. Just insert Mary Lou instead of Freddy. In fact at times plays out a little bit like, but works better than A NIGHTMARE ON ELM STREET 2: FREDDY'S REVENGE (which was made 2 years prior). Certainly worth a look.
