As the body count rises, the remaining partygoers must fight to uncover the killer's identity and survive the night, realizing that their costumes might be the only thing hiding them from a gruesome fate. This isn't just a spooky Halloween flick; it's a suspenseful slasher where no one is safe, and the masks might be hiding more than just faces.
