It is the story of a man who tries to challenge all things through his desire for his professional life as a crime scene cleaner. One day, this man is exposed to a strange situation in front of a job where there appears to be murder and is linked to a dangerous network of games.
It's not that Cleaner is a terrible film, it just doesn't rear back and sock the viewer in the jaw like a great thriller should. It's mild sauce from the first frame to the last.
