Halloween didn't turn out how it used to be when Emliy and her five friends found an abandon mansion in the woods.
Now, they're stuck in the woods and can't find a way out. That Halloween turned to be a death game. If Emily can't find her friends in an hour, that night will be their last Halloween night.
When Skylar's party girl best friend, Stephanie, decides to throw a party, nothing seems out of the ordinary. But when Steph's usually packed party gets only a few people, they should've just decided to leave. Leave the woods. Leave the old building that Steph's father recently bought. Leave as soon as they noticed someone, or something, was stalking them in the night. They should've left because this was quickly becoming a big mess of a party.
