The owner of the event agency Darina and her restless assistant Slavik, who dreams of detective glory, are faced with two things at once: to find out whether the wife of Major Anatoly Kameshkov is faithful, and to unravel the mystery of the disappearance of the black cockerel. The newly minted detectives will have to experience village life, fall in love, believe in the Black Messenger of the Dawn, find a corpse and unravel not only a tangle of deaths, but also a long-forgotten accident case. It was during this difficult period that Darina really needed the help of her eccentric mother and three fathers: a police lieutenant colonel, an authoritative businessman and a leisurely philosopher. Yes, Darina has three fathers. And all the relatives. Is this really possible?
