A man, his wife, and their son live in a suburban area, along with a trustworthy housekeeper and an itinerant gardener. They have an electronic gate and alarms in case anyone trespasses.
The parents agree on getting a coil of metal laced with broken glass that is placed on top of the wall. Anyone who tries to climb over will get extremely hurt.
DO NOT ENTER YOU HAVE BEEN WARNED
The family's area is in a state of rioting and robbery. The family becomes paranoid and they buy a taller wall, so burglars won't climb over. The husband's mother pays for the wall as a present and also gives the son a Space Man outfit and a book of fairy tales.
The family cat easily jumps over the new, higher wall and the parents bemoan robberies even more.
The family's son wanted to reenact Sleeping Beauty from the boy's fairy tale book. He climbs into the coils pretending that they are the thorns blocking Sleeping Beauty's castle.
The boy gets stuck and gets severely scratched up. He starts bleeding excessively. Everyone in the house notices and carries the bloody body inside the house.
