I wonder if this cabin will be as fun as it sounds?
"This is gonna be SO much fun!"
"I'm not so sure about this house."
"You guys! Look at this sign! What do you think it means?"
BEWARE THE SENTINEL!
In the beginning, Duffy (left) was found to be very forgetful. He forgets everything, and his family has to remind him to pick up his things. The family decides to take a vacation to get away from the stress, and so they are on their way to the cabin that their aunt's boss's friends who had a friend loaned them.
"Do you feel like someone is following us?"
"Yes. . ."
The family arrives to the cabin. The main character is upset because this is not what he pictured. The kids thought the cabin would be much nicer.
"Do you guys hear that scratching noise coming from the door?"
The main character realizes the inside wasn't much better either. He also finds in large letters, "BEWARE THE SENTINEL". He is scared, and tells his siblings that he is worried about staying here because of the little note on the wall.
"And that's my jacket that I left in the woods! That's how he found us! I knew it!"
Duffy leaves things everywhere, and if someone doesn't remind him, he leaves it there. After a long walk deep in the woods, the kids feel like they are being followed. They become worried, and ran home not worrying about Duffy forgetting something in the woods. Duffy leaves his blue jacket in the woods, not realizing what trouble this is going to cause later.
With their parents gone, the kids pass time by playing board games. They hear a scratching noise coming from the door. The kids immediately freak out and think its the Sentinel. The kids run to and fro trying to escape from the monster.
The mysterious monster approaches the door, and knocks it down. The kids scream, and see the Sentinel holding Duffy's jacket which he had left in the woods. All because of Duffy's carelessness, the Sentinel tracks down the kids with Duffy's jacket.
