The year of 1940. Nikolay Slavin and Semen Zubov, civil pilots, love the same woman - Elena. Slavin is a quiet and reasonable person, Zubov - on the contrary, impetuous and risky. Elena being Slavin’s wife wishes to leave him for Zubov, as her husband seems too dull to her and Zubov - romantic. However reckless Zubov is barred from flights, and Slavin works slowly but surely to set up a record - high-altitude flight at full load. Elena understands her mistake in time.
