Denis Dubov is a professional cleaner: he cleans crime scenes and gets rid of traces of murders, so he knows too much. But even taking refuge in a small southern town, he continues to attract trouble. So on his doorstep there is a thunderstorm of local crime, a harsh but fair investigator Diana and her not the smartest, but persistent assistant Hajdukov. And to prove his innocence, the cleaner will have to challenge the entire criminal district.
