Brief Description  Night of the Demons (1988) is a quintessential supernatural B-horror cult classic directed by Kevin S. Tenney and written by Joe Augustyn. Originally developed under the title Halloween Party, the film is highly regarded for its quintessential 1980s "spooky season" atmosphere, over-the-top practical special effects, and dark humor.

Plot:
On Halloween night, a group of high school students decides to bypass traditional neighborhood festivities to attend an alternative party. The gathering is hosted by the school's eccentric goth outcast, Angela Franklin, inside Hull House—an isolated, abandoned funeral parlor rumored to have a cursed history. Hoping to scare her guests, Angela leads the teenagers in a past-life séance in front of a large mirror. The ritual goes horribly wrong, inadvertently unlocking and awakening an ancient demonic entity trapped inside the crematorium. The malevolent force seals the teenagers inside the unhallowed grounds and begins possessing the partygoers one by one, transforming them into grotesque, bloodthirsty monsters. The remaining unpossessed survivors are forced into a chaotic, gory battle to preserve their souls and escape before dawn.
