Jane, the fashionista, is dressed in an intricate Marie Antoinette gown, Mike is a convincing Frankenstein's monster, Tim is an intimidating pirate, and Sarah is a glamorous witch.
On the way to the party, they stop at a gas station in the middle of nowhere where they encounter a strange man named Herman.

Ignoring his warning, they continue on their way, only to find themselves stranded when their car breaks down.
With no other options, they begin to walk through the woods and stumble upon a creepy old mansion. As they enter, they realize that this is not a normal Halloween party but a sinister gathering of monsters and maniacs.
