One day the usual order of one of the country's major airports is disrupted: pilot Zubov lands his plane during the fog accurately and beautifully, but contrary to regulations. Another daredevilry of Zubov ends with the fact that he sinks the plane in a swamp, almost killing himself and the adopted son of the airport engineer - Gvozdik. Zubov is deprived of his pilot's license for six months, but is retained in the team.

A young engineer named Zotov has been appointed head of the 406th picket line at the construction of a railway line in the taiga. The construction workers huddled in a smoky, dark dugout did not welcome the new foreman very cordially: not everyone can do hard work and household disorder. But the day came when the builders occupied the house they had built themselves, and Zotov had a double holiday — the bride arrived. And again it's weekdays, and again the cold barracks is full — a new batch of builders has arrived.
