Every 5 years the police visit 10 nearly-randomly chosen houses. An obstacle course is set up in the house's garden. Ahylia and her little brother Jeff invite Sam, their neighbour round for the day. An old policeman is sitting on a deckchair. Ahylia, Jeff and Sam complete the obstacle course. Ahylia and Jeff's dad's at work. Their mum goes to the supermarket. The trio are alone with the policeman. He kidnaps them, leading them down a manhole cover and into the pitch black sewers. They take a turning behind a locked door and the three kids find a place where they will be forced to work until they die.
