Andrew, Duffy, Marie, Aunt Elise, and Andrew's mother all looked around their vacation house. No one liked the house except for Aunt Elise, Andrew hated the thought of having to stay here.
After the family goes to bed and wakes up in the morning, they go wading in a river that they found. When they come back Andrew decides that he wants to look around. He goes in a room and finds " BEWARE OF SENTINEL" written on the wall.
Beware of sentinel
When Andrew shows his mom the writing, she thinks nothing of it. After that, all of them decide they want to go on another walk. When it gets hot they want to take their jackets off..... but no one reminded Duffy to hold on to his. When they get home they realized that Duffy had left his jacket out in the woods.
The crew has come back from their walk and the parents decide they want to go to the store and eat out. Once the parents leave, the kids start playing Monopoly. They are playing when they hear something at the door. There is a scary figure outside the door scratching at it.
When they hear the scary figure at the door they decide they want to go outside and run from it. They venture out to the barn but the barn is locked! The scary figure is coming closer to them so they have to think fast. They then go back into the house and try to hide from from the scary figure.
When they go back into the house they go upstairs to Andrew's room. When they go up there they see that the figure is coming back to the house. It starts to come up the stairs and scratch at the door. The door opened and the figure was holding Duffy's jacket. It throws the jacket at them and says," You forgot your jacket stupid."
