On the outskirts of the provincial town, Yevdokim and Yevdokiya live, raising foster children. Yevdokim works at a factory, Yevdokiya is a housewife. The family seems to be safe and happy: the only trouble is that Yevdokiya cannot forget the love of her youth. This Yevdokim cannot stand and offers Yevdokiya freedom, while he will remain with the children. But all these contradictions are drowned in mutual love for children and for each other.

In a small seaside town lived two friends—the feisty Fedka Boiko and the thoughtful, quiet Vovka. One day, the boys called a doctor to visit a sick person and began to visit him. That is how an extraordinary person entered their lives — polar pilot Pavel Ivanovich Fedoseenko, who turned out to be a shortwave radio amateur. From him, the boys learned about distant Antarctica for the first time — and vowed to become polar explorers. In the Antarctic village of Mirny, polar explorers Vladimir Sazonov and Fyodor Boyko meet—old friends who haven't seen each other in many years, who reminisce about their childhood in a southern coastal town and the romance of long-distance radio communications on short radio waves.
