Major Zygmunt Grela is an aviation ace in his unit and a strong candidate for the commander's deputy. At the last moment, however, this position is taken by major Horycki. Grela is trying to hide his disappointment, as Horycki is his good old friend. However his mental condition deteriorates soon, when he learns, that is sick and won't be able to fly anymore. The relationships between both protagonists became finally really tense when old feeling between Grela's wife and Horycki is starting to revive. Whether their friendship will survive, despite all those adversities?

Similar situation like above.
