Shulick Dimufiev, a young and promising scientist, devoted himself to experimenting with scientific inventions at home, and again and again, three, three, four and five. The power went out in the apartment where he lived. Ivan? Comrade Vasilyevich came to complain on behalf of the broad masses of the people, but he dragged him into the first flight experiment of the newly invented time machine. At the same time, during the burglary of the dentist, Miloslavsky happened to meet the two people who took part in the "close maiden voyage". Under several tricks, the three men crossed to the palace of Ivan Redi in ancient Russia. The czar, who thought the demon had arrived, fled and entered the modern era under the chase of Shulick, while Comrade Ivan and the thief were chased back and forth in ancient times. The time machine was accidentally damaged in the chaos, and because of his resemblance to the czar, Comrade Ivan was unwilling and had no choice but to follow the advice of the thief, pretending to be the "Thunder" emperor and dealing with the people. On the other hand, the czar stayed at Shulick's house, undoubtedly creating a series of misunderstandings and confusion.
