The curse of the Vasnetsovs overtakes the already grown-up daughters of a family psychotherapist. On the eve of the next wedding anniversary, Dasha runs away from home, leaving the workaholic Veniamin a farewell letter, an engagement ring and four daughters. Now Veniamin, just like his father-in-law once, is forced to become father, mother, and friend for his children. And the resilient Vasnetsov family will help him in this.
A young man from the noble Bezsonov family — Nikolai — by chance and at the behest of his heart becomes an ordinary official of the detective police. His colleagues receive him coldly, and only an experienced official, Pyotr Romanovich Shchukin, sees in the young man the future star of the investigation. Together they are trying to uncover a chain of mysterious and dangerous crimes committed either in the city slums or in the boudoir of a socialite.
