Muneri Kiyoshi is a company man supervisor who has trouble getting a good night's sleep. Moguro gives him a small electronic pillow to attach to his neck which will allow him to sleep while appearing to be awake. However, Muneri must remove the device when a buzzer sounds to avoid overuse, but he ignores the buzzer and it overloads during a business meeting. He then finds his inability to sleep ideal for his new position, as night watchman.
