An experienced civil aviation pilot cannot imagine life without sky. But he is forced to resign. Nice home, happy family... and a deadly disease, like an echo of the past. Past, in which he made many mistakes. The sky does not let him go until the very end. And it is in the sky that his life path ends. And a new one begins - in the distant past, in the body of a seventeen-year-old teenager whom he once knew. Fate gave him the opportunity to correct past mistakes and live life anew. But once you rise into the sky, you never want to return to earth.
