Strong-willed Olga Nikolaevna is the boss at home and at work. The only one who breaks the order in her life is her son-in-law-like nothing else. Then one day, the flurry of mutual claims becomes so great that right on a family holiday, the situation gets out of control.

Viktor Suslov finds himself back in the maelstrom of family passions: now he lives under the thumb of a new mother-in-law, with her single-handedly established rules and strict house rules. An already difficult life is disrupted by the sudden arrival of Viktor's twin brother, Tokha. The domestic "idyll" is bursting at the seams when, not without the participation of the mother-in-law, the former enmity of the two brothers flares up again. The situation is aggravated by the appearance on the doorstep of FSIN officers looking for Tokha.
