The son of oligarch Sylvestre Sergeev, Sasha, fled from the university in London, where he studied finance, and entered the astronomical department of the physics department of a Moscow university. Sylvester Andreevich wants to return his son to his former life, but he wants to live "among the people" and wants to achieve everything in life himself.

The "Big Difference" is created not only for the audience, but also for those who became the hero of the parody - TV presenters and actors. A guest who comes to the studio seems to see himself through a magnifying glass, because all the details are taken into account in the parody: the character's manner of dressing, speaking, diction features, plastic, makeup, hairstyle. The uniqueness of the project is that in addition to entertainment, the program also has a developmental function. After all, our guest, who is being parodied, has a chance to look at himself from the outside, to see his shortcomings and advantages. Some people like themselves, and some don't. But the main thing is that no one remains indifferent.
