The film begins in Thailand, on the ranch of Igor's father, and continues in Moscow. Igor invites friends to the ranch to introduce Nastya to his father and to have a good time. On the way to the plane the friends get acquainted with a young American family that is going to one of the monasteries to recover from infertility. Igor, Artem and Sauna try to dissuade their girlfriends from visiting the monastery, but without success. An ancient idol is located in the monastery, which according to the legends, grants paternity to anyone who touches it. Despite the monk's warning, the friends still make physical contact with the idol and are now doomed to conceive a child at the first sexual intercourse. Afraid of this, they temporarily decide to refrain from sex, which causes discontent of their sweethearts, who become offended and leave. Igor's situation is aggravated by the fact that his father is an oligarch against his relationship with Nastya and wants to arrange a profitable marriage for him in order to fix his financial affairs, and Nastya learns about this with all the ensuing consequences. The guys decide to spend the rest of their time in leisure, but then they meet their old friend — Saint Valentine, who puts a new spell on them — only one of them will become a father, and the rest will be able to have a child no earlier than in 10 years. The guys realize that they are ready for paternity, and adventures begin.[6][10]
