What should you do if a neighbor bursts into your home, throws a tantrum, cries, and then goes to sleep in the guest room? At first, Dasha Vasilyeva decided that her neighbor, Kirill Gabuzov, was simply sick. But the situation cleared up when his wife, Vera, explained everything. It turns out their son, Benjamin, is missing! And now the parents are in panic, because the teenager left all his medicines at home and will surely die if he doesn’t take them in time.
Dasha decides to help the neighbors search for the boy. And then it all begins… Lesya, the missing boy’s sister, for inexplicable reasons does everything she can to interfere with Dasha; a coffin is unexpectedly brought into the house; and the floor clock attacks Degtyarev and almost chops off his head with an ax… But for an amateur of private investigations, nothing is impossible. She will uncover all the secrets of this strange family.
