Released in 1980, the '''''Prom Night''''' opens with the unfortunate death of a child, when a group of kids playing a variation of hide-and-seek in an abandoned building teases a girl and she falls from a window. The kids never told anyone what happened and the little girl's death was blamed on Leonard Murch, a psychopathic child molester who is caught shortly after.

Several years later, students of Hamilton High are preparing for prom. But unbeknownst to them, a masked killer looking for revenge has invited himself to it.

The film features JamieLeeCurtis and LeslieNielsen in starring roles. Nowadays, the film is mostly remembered for its [[CultSoundtrack disco soundtrack]], which is sought out by collectors. It was also popular enough to receive three sequels; ''Film/HelloMaryLouPromNightII'', ''Film/PromNightIIITheLastKiss'' and ''Film/PromNightIVDeliverUsFromEvil'', and [[Film/PromNight2008 a loose remake]], which was released in 2008.
