In the original Prom Night, a group of children–Wendy, Jude, Kelly, and Nick—inadvertently kill a young girl named Robin during a game.

Six years later, Robin's elder sister, Kim (Jamie Lee Curtis) and her fraternal twin brother, Alex, are planning to attend her senior prom at Hamilton High School.

While searching for a dress in the school's costume room, she discovers a trunk full of mementos and clothing that belonged to Mary Lou Maloney, a teenage student who was burned to death during a prank while being crowned prom queen in 1957.

As Vicki is crowned prom queen, Bill shoots her, after which her body morphs into the burned corpse of Mary Lou.

Mary Lou wreaks havoc, but is placated when Bill places the crown on her head; she kisses him, and disappears.

Their party is crashed by Father Jonas, a Roman Catholic priest who murdered two students at the 1957 Hamilton High prom before being sequestered away by the church, apparently possessed by a demonic spirit.

Meagan ultimately beats Jonas before leaving him to burn to death in a shed, though he awakens while being transported to the morgue.

In the 2008 reboot of Prom Night, high school student Donna Keppel (Brittany Snow) is traumatized after Richard Fenton (Jonathan Schaech) becomes obsessed with her and murders her family.

At her high school prom, held in a grand hotel, Fenton arrives and stalks her, disguised as a stranger, having escaped from incarceration.

A chase ensues, but she is ultimately saved by Detective Winn (Idris Elba), who shoots Fenton to death.
