Frustrated by the institute’s bureaucratic meetings, Bantikov secretly shifts his focus to a side project: designing and building a humanoid robot named Yasha.
Despite his logical precision, Yasha's interactions with people reveal his lack of humor and emotional depth, drawing attention to the robotic tendencies of some humans Bantikov encounters during the search.
Eventually, Yasha is found and reassigned as an instructor at a seaside sports base, where his literal-minded nature leads to comical situations, such as chasing vehicles for fuel to keep his motor running.
Unable to subdue Yasha through conventional means, the institute staff resorts to trickery, luring him into the sea, where a short circuit disables him.
The film concludes on a triumphant note: Bantikov’s experiment succeeds, Yasha evolves into a more human-like being, and the institute achieves breakthroughs that pave the way for new scientific challenges.
