Investigator Gleb Karpov, while visiting his hated mother-in-law, accidentally learns that the old woman is condoning his wife Svetlana’s meetings with a certain Georges. Right on your own territory. Karpov is furious! The vile pimp also adds fuel to the fire. Like, a young neighbor lives above her, and she and her son-in-law are very compatible in character. The meeting with Christina makes an indelible impression on Gleb. The whole next day he wanders aimlessly around the city and eventually ends up at a familiar entrance. And on Monday, Svetlana, swearing and sobbing, reports the murder of her mother. Well well! Gleb would now be able to rejoice little by little. But that was not the case: his wife accuses him of the crime!!!
