Two representatives of an extraterrestrial civilization are sent to Earth to find the Emperor's missing son and help him complete a secret mission. The aliens mimic humans and pretend to be an ordinary couple, Anton and Marina. In order not to attract unnecessary attention, they try to do the same things as those around them: go to work, communicate with friends and colleagues, and do everyday life. At first, the aliens have a very difficult time. However, they gradually get used to it, and Anton sees more and more advantages in earthly life and does not want to return to his home planet.
