After a test flight, pilot Sergei Sazonov was invited to a group of astronauts. Intensive preparation begins for the flight into space: classes in the weightlessness chamber, constant study. Sergei decides that he does not have the right to meet with a cheerful student Natasha, whom his friends accuse of frivolity. But their telephone conversation ends up asking him to marry him.
