In a small town in the United Mexican States , professional wrestler "Snail Man" lives with his wife, two children and his father. This morning was the same as every morning before. After breakfast as a family, "Snail Man" reads the newspaper and drinks coffee, which is the only precious moment to forget the hardships of being a wrestler. The wife noticed that her husband seemed a little different. The opponent in today's game is a famous rookie who is twelve years younger than him and full of energy, and the "Snail Man" is not just because he is worried about his opponent. He is inexplicably disturbed, and his intuition tells him that something will happen.
Meanwhile, a man in a strange polka-dot pajamas wakes up to find himself locked in an empty room with white walls on all sides. What is this place? Who is this man? Who was he locked up for? Everything is a mystery.
The man in pajamas ( played byまつもとひとし) looked around and couldn't see the doors and windows, desperately looking for an exit. When he hit the wall, a strange thing appeared.
