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.
In 1942, local teenagers are organizing the underground resistance in the city of Krasnodon during the Nazi occupation of Russia. The teens manage to outsmart the Nazis in their fight, and their activity lifts the spirits of the surviving citizens.
