A man trapped in an endless sterile subway passageway sets out to find Exit 8. The rules of his quest are simple: do not overlook anything out of the ordinary. If you discover an anomaly, turn back immediately. If you don’t, carry on. Then leave from Exit 8. But even a single oversight will send him back to the beginning. Will he ever reach his goal and escape this infinite corridor?

An unknown person has started a mysterious "ceremony." It is something that already exists before meaning is even born. Once begun, it cannot be stopped. Is it a blessing, or a ritual of farewell? And where does the answer lie? The film portrays the story of one such "ceremony" that exists somewhere in the world.
