The action takes place in the Moscow region in an old noble estate, built almost 200 years ago by Scherbatov nobleman. After the October Socialist Revolution and until the end of World War II, the manor was empty. From 1945 to 1953 a special reception center for children of “enemies of the people” was located here. Then from 1953 to 1980, orphanage No. 8 began to work there. After its closure, the manor was again empty for exactly 20 years. At the end of 1999, the building was bought out under a private elite boarding school, in which the action unfolds today. The series tells about the life of students and teachers of the elite boarding school "Logos", located in the old estate of Shcherbatov nobleman in the midst of a gloomy, but picturesque forest. In their closed world, all experiences are much more acute than in ordinary school life. In the story, throughout the series, there are eleven main characters. In the course of the plot, it turns out that each of them has its own secrets and skeletons in the closet.

The mayor of Moscow sends a crazy daughter to teach geography to high school students. To increase her father's rating, a brash and moody girl will have to get closer to the residents of the city and make friends with teachers.

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.

Karen Magikyan is almost 50 years old. He is the head of the family and the father of three daughters. At this age, people do not change. He has long formulated laws and rules by which he lives, and is not going to break anything. It seems to him that for the last 10-15 years he has not changed a bit, he has not aged a bit. Moreover, he considers himself to be quite a modern person, although he has a mobile phone with a black and white screen and no email. This, by the way, is especially annoying to him - why everyone is going crazy about these gadgets, iPads, iPhones. Why is the younger daughter, after returning from school, immediately goes to the Internet, and not kiss her father? To “communicate” is to sit at the table, drink wine and talk, and not stare at the computer screen and spoil your eyes. He does not understand modern relationships. How can a daughter stay overnight when they are not married? And he does not care about the assurances of his wife that "now everyone is doing this." Let everyone do that, but not in his family! He is Caucasian, he has principles! Karen - The Last of the Magikians. And not only because he has three daughters, and an heir at that age is clearly not foreseen. He is a representative of an endangered species of people who have never spoken on Skype, for whom a letter is a paper written in letters in an envelope, and most importantly, who do not bend under a changing world, because “now it’s accepted” and “you live in the 21st century ". Younger viewers should recognize their parents in him, older viewers should recognize themselves in him.
