Andrew, Duffy, Marie, and their moms left late one Friday in October. They were on their way to stay in an abandoned cabin surrounded by woods.
The family arrived and looked around the place. Andrew went into the room he was staying in and found a note on the wall that said, "BEWARE THE SENTINEL."
The 5 took a walk through the woods. As they were leaving the woods and Duffy dropped his jacket.
You forgot your jacket, stupid.
The kids' moms left for a drive into town. The kids were playing games and eating popcorn when they heard a faint scratch scratch on the door.
They realized the creature was trying to get them. They decided to take off for the barn.
The three kids ran up the stairs and into Andrew's room. The sentinel followed the kids and stopped once the boys looked at him. He said, "You forgot you jacket, stupid. The sentinel turned and walked out.
