'''''Prom Night IV: Deliver Us From Evil''''' is a SlasherMovie from 1992.

A [[SinisterMinister psychopathic priest]] who seeks to 'save' what he perceives as dirty and tainted, Father Jonas kills two Hamilton High students during the prom night of 1957 (the same night [[Film/HelloMaryLouPromNightII Mary Lou burned to death]], talk about a bad night). After several failed attempts to help him, the church places him in a sedated coma. Over three decades later, he awakens and promptly continues his mission to kill those whom he perceives as sinners.
