A respectable family decided to transport their father’s ashes to the Promised Land. However, when the grave was opened, two more skeletons were found in it. Who were these people illegally buried here? Why did they end up in someone else's grave? The investigation of this seemingly hopeless case was entrusted to the investigator for especially important cases of the Moscow Prosecutor's Office, Klavdia Dezhkina, and a young intern, Irina Kalashnikova.
