A young scientist in the field of space medicine is sent to the Antarctic station "Vostok", the coldest point on the planet, to study human vision in extreme conditions.

And the hero asks himself the question, is a person ready for deep space flights spiritually, and not physically?

François Dembele was born in Africa and since childhood dreamed of being a scientist, living in the Soviet Union, a small paradise, as it seemed from the depths of the sandy continent.

He believes that the main thing in life is the formation of the soul.
