Put together a dynamic new director, a great script, a dose of black humour, a love story and a pinch of action and, voilà – you've got a cult movie! Kazuhiko finds a job in a public toilet, but by a cruel quirk of fate it also turns out to be the place the Yakuza use for their executions. And when the young man discovers the truth, he ends up assigned to the night shift - which includes getting rid of the bodies.
