The heroes of the film are a polar explorer, the head of the North Pole drifting station Tomas Petrovsky and his mother Romualda Flerovna. The scenes are the Arctic drifting station SP-33 and the Belarusian village of Petrovskoye. An eternal story about a son who leaves home for no reason, into an incomprehensible and dangerous cold, and about a mother who does not understand him, loves him and prays for him. And here, at home, there is paradise, buzzing bees, a blooming garden, a clean river, warm earth.
