 A man in a suit is sprawled on the floor of an office. Colleagues help him to his feet. The next morning, he remembers his name (Shiode) and where he works, but he doesn t remember yesterday. That evening, he adjusts his camera to take photographs automatically and leaves a sign on his suit - "take this camera to work." For several days, while the camera makes a record, Shiode rises, leaves his apartment block, takes the train, works at his computer station, buys food at a convenience store, and eats at home. He has the photographs developed, and all is revealed.
