The fun company is students Stas, Pasha and Venia. Stas is a lover and a chatty hero, his fascinating stories and jokes captivated more than one girl's heart. Pasha is trying to depend on no one, he started working at the school, and now works as a "balloon owner". Venia is a computer genius, technology replacing him with all the joys of life. But all of them are united by ingenuity, agility and desire for different adventures.

The guys are brilliantly finding a way out of any, even the most critical, situation. Yet sometimes they lack the flexible girlish mind. Therefore, Margo appears in their friendly team. She came to the capital to visit her father, who divorced her mother several years ago, and works as the director of The Last Writer.

The girl wants to join one of the Moscow universities and move to the capital for study and adventure. After all, she had such wonderful friends.
