Sergey Sergeevich decides to test the robot in the human environment and sends it on a date with the bride of one of his employees Tatiana (Marianna Vertinskaya).

However, Robert "falls in love" with her and readily fulfills all, even the most ridiculous and dangerous tasks of the girl, because he understands all her orders literally.

The robot goes out of control - it even disappears from the field of view of scientists, going after Tanya in a mountain camp.

Scientists understand that using a robot in an unknown and unpredictable environment is unsuitable, and a man is preparing for the space flight.

"Mountain" episodes of the film were shot in the Caucasus, at the base of Mount Elbrus.
