It's Halloween, and the students of Richmond High are out trick or treating. And, as usual, Robbie Colbert has gorged on his favourite Reese's chocolate, making him sick to his stomach and annoying his friends no end.

But he doesn't let that stop him from entering the house at lot 666 on Derbon Street. Yes, that house. The house that every man and his dog avoids regardless of what day it is. Puffed up with bravado, Robbie decides to enter the property in search of more candy.

When he doesn't return, his best friend, Pete Wells, goes in after him, and when he doesn't return, Jasmine, Anna, Bella and Kyle seek help. Finding none, they reluctantly go in after their friends.

Then the nightmare begins...

A twisted game of trick or treat, starring a dancing pumpkin, a chocolate- gorging hell beast, and an old man who just wants it all to end. And with round after round of questions the children must answer correctly to stay alive, the night continues to turn from one horror to the next.

Can they make it out alive, or will they be gorged on like one of Robbie's Reese's Peanut Butter Cups?
