Two women: a mother and her growing daughter, both of whom love the same man. Mother-husband, daughter-stepfather, who is both a friend to her, and Doctor Pilyulkin. In their desire to attract his attention, they fight among themselves as if they were not relatives. The mother, not thinking about the consequences, the daughter, luring her with her youth and body... And the daughter wins! But...What about him, can’t he really see? She sees, understands, and refuses her daughter... Time passes and Galina, the one who thought she won it, is already flying as a flight attendant on Ilya. And their plane, Il-18D, once caught fire because the crew quarreled with the navigator, a walking woman, so much so that they landed with the landing gear not extended... They quarreled to death, and then they chickened out, leaving the burning plane... And then Galina, in the image of a savior angel, saves passengers at the cost of her own life.
