Based on the hit phenomenon game, EXIT 8 is psychological horror from Genki Kawamura (producer of Monster, Your Name., Weathering with You).

When a man (Kazunari Ninomiya) finds himself lost in an endless maze of subway tunnels, he quickly realises that he needs to reach Exit 8 to leave. But in order to do so, he must follow three rules that will set him free: do not overlook anything out of the ordinary. If you discover an anomaly, turn back immediately. If you don’t, carry on. But as each mistake he makes brings him right back to where he started, an infinite loop of trial and error is created as he tries to escape.
