After two years spent in jail, UPC investigator Ivan Shamanov is released. He has a son, colleagues, excitement and work, as well as a bad temper and a great sense of humor. He is loving - and the beauties reciprocate him. His main enemy is Korneev, the man who put the Shaman behind bars. The shaman is too cool in his profession - and this cannot leave those with whom he fights indifferent: criminals are afraid of him, intimidate and try to remove him. But the Shaman knows for sure that the power lies in the truth. That's why he's always one step ahead of the villains. But who will win in the end?
