A path with no beginning, no end.

A man with a life-changing decision to make finds himself trapped in a seemingly infinite corridor in a Tokyo subway station. Each time he passes through the sterile, quiet hallway, he discovers himself back at its beginning, walking past the same doors, the same posters, and disturbingly, the same people, as he did the previous time. He soon discovers that in order to reach the elusive "Exit 8", he must look more closely at his surroundings, and notice the tunnel's bizarre anomalies.

Spot one, and he must turn back. Spot none, and he can proceed.

Make it to eight, and he'll be free. Make a mistake, and he must start over again.

As he stumbles through an endless loop of conformity, confronting the strange, new possibilities of his own life, he begins to wonder if anomalies are not things to be feared but to be embraced. Maybe, he thinks, the only way out is through.
