A man wakes up and mysteriously finds himself trapped in an empty, white rectangular room, wearing clownish bright yellow polka dot pajamas. Where is he? Who did this to him? How did he end up here? Will he manage to make him escape to safety? Meanwhile, in a Mexican dusty town, a green-masked wrestler known as Escargot man prepares for an important match. As the nameless prisoner appears closer to escape and Escargot man steps into the ring, filmmaker Matsumoto amplifies the baffling yet suspenseful atmosphere to a crescendo of ridiculous excess.
