Made as Prom Night IV, this has been retitled because, with the exception of being set in the same school, it has nothing to do with the earlier films in the Canadian slasher series. Kept in a chemically induced coma since a 50s murder rampage, a demon-possessed priest wakes and sets out on prom night (surprise) to menace and murder sinful teens who have retreated to an isolated old house for booze and bonking.
Despite its unusual Catholic undertone (much talk of confession and sin) and better-than-average teenagers (especially Bridget Fonda lookalike Joy Tanner as the cheerful slut), this relies too heavily on predictable death-by-death plot developments, and a pony-tailed mad-eyed male model in a dog collar hardly makes the most threatening of movie maniacs
