Evgeny Korolev arrives in Moscow by train and meets his future friend there - a red-haired first-year student Vladimir Vladimirovich Kvakusha. In addition to this guy with a funny last name, Zhenya recognizes Sasha, the head of the first-year students, who falls in love with him without memory. However, Zhenya himself falls in love with a third-year student, Veronika, whose boyfriend, Anton Sedykh, has great ties with the deputy dean Pavel Ilyich Gusev. As for Gusev, he hates Dean Vesnovsky and wants to take his place with all his might. Gusev's behavior affected not only teachers and students, but also Evgenia: he was once expelled from the student dormitory. However, he remembers that he has a friend Kvakusha, who is always ready to help him: the whole problem is that Kvakusha is a master at creating problems, and it is very difficult to solve them later.
