In 1921, the Cheka became aware that gold and jewelry were stolen from the treasury of Gokhran, and that a special organization was involved in transporting the stolen to Estonia. Scout Maksim Isayev is sent to this country. He establishes that the cipher of the Soviet embassy Olenetskaya works for the German resident Nolmar, with whom employees of Gokhran Kozlovskaya and an appraiser Yakov Shelekhes are associated. As a result of the provocation, Isayev was arrested. In the prison cell, he finds himself together with the famous Russian writer Nikandrov, who could not find himself in post-revolutionary Russia and went abroad. Released soon by the efforts of his comrades, Isayev continues the struggle for the fate of Nikandrov — for his return to his homeland.
The film consists of three independent parts: "Workmate", "Déjà vu" and "Operation Y". The plot follows the adventures of Shurik (alternative spelling — Shourick), the naive and nerdy Soviet student who often gets into ludicrous situations but always finds a way out very neatly. "Operation Y and Shurik's Other Adventures" was a hit movie and became the leader of Soviet film distribution in 1965.
