Experiences and problems of an air squadron: Commander Milan has reached the age limit for pilots and must come to terms with the fact that he will have to give up flying from now on. Lieutenant Lenz loses control of the plane during a flight and is seriously injured during the parachute rescue, in the worst case scenario he remains paralyzed. He doesn't want to tie his girlfriend Anka to him, but she sticks by him. Young Kullas comes into the squadron to replace Lenz. His predecessor's accident makes him afraid and he tries to find out what courage means to him. Lieutenant Herzog loves the teacher Sigrid. She returns his love, but it is difficult for her to choose a "hero" once again. Two years earlier, her husband was killed defusing a bomb. But Herzog does not want to give up his job. The fifth, Captain Wendland, is a party secretary. He takes flying just as seriously as his concern for his comrades.
