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 this comic but dated story, nerdy Shurik travels to Caucas in search of native legends and folklore. But what he finds is a beautiful girl whom, due to intoxication and deceit of the local "gang", he ends up literally stealing for the local deceitful governor. All the time Shurik thinks that it is all just a one old Caucasian custom. When he, finally, realizes what he did he goes out in search for the girl of his dreams. Written by Ptah Hoteb
