Kawashima Masayuki is a successful graphic designer living in Tokyo with his loving wife, Yoko, and their baby girl.

One night, as this struggle unfolds once more, Kawashima makes a decision to confront his demons and sets into motion an uncontrollable chain of events seeming to lead inexorably to murder.
