Private detectives Makar Ilyushin and Sergey Babkin, specializing in the search for missing people, are hired by Andrey Krasilshchikov - a real ascetic who invested all his money and soul in dilapidated ancient tower in the village of Kamyshovka and restored independently. Then Vera Bakshaeva, the sister of the former owner, from whom Andrey bought the house, came to him and claimed the tower had actually belonged to her and threatened to take it away. Panic-stricken Krasilshchikov, being afraid to lose the goal of his life, attacked the woman in a state of passion and was sure he killed her. Having come around, he went to the police giving himself up, but Bakshayeva was never found, neither alive nor dead. Andrey cannot live with such a weight sitting heavy on his heart and asks the detectives to find the Vera who was killed by him. Makar and Sergey begin investigation and soon understand that the locals of Kamyshovka aren't glad to see them at all. Which means they have something to hide.
