The film follows Chris Vale, who was admitted to an asylum at the age of 12 after witnessing his mother's rape and murder by two thugs hired by his father (who subsequently committed suicide).

Vale kills a party-goer named Todd at a gas station, steals his costume and car, and drives to the party.

He breaks up a hole in the wall covered with boards where his father hid his mother's corpse before committing suicide.

In the final scene, Vale is seen hitch-hiking and picked up by a car driver, who presumes him to be having a long Halloween party night.

"[2] Dread Central also heavily criticized the film, stating "Halloween Night is stupid slasher flick that’s sporadically amusing but mostly dull due to pacing issues, the predictable nature of the “seen it a million times before” storyline, and its insistence on taking itself far too seriously even when it's being outright dumb.
