Dima is preparing for the birth of his first child and is confident that he has thought of everything. But on the most important day of his life, things begin to spiral out of control: the baby arrives early, and, just before that, his own father—who had vanished more than twenty years ago—suddenly reappears. At the maternity hospital, Dima finds himself in a waiting room with four other men, all of whom are completely different from one another. Andrei, thirty years later, is getting a second chance at fatherhood, yet he fears repeating the mistakes of the past. Young DJ Arseny must learn to embrace not only his own child but also the son of the woman he loves. Gena, a hot-headed construction worker, has spent years trying to have a child with his wife, while Mikhalych has decided to become a father later in life. Over the course of a few hours, these chance acquaintances argue, bicker, share their deepest personal fears, and end up forming their own "Fathers' Club."
