About
Soviet television feature film of 1981, a three-part historical detective. In January 1918, one of the most notorious crimes of the first years of the Revolution took place - the Patriarchal sacristy of the Moscow Kremlin was robbed. The investigation is conducted by the young Soviet police in cooperation with an "old-regime" investigator-professional. But the unique diamonds and icon frames seem to have fallen through the ground. The investigators have only one thread - dropped by someone under the windows of the sacristy snuff box with the family coat of arms Messmerov.
