The film tells the story of three wartime fighter pilot friends—Vasily Bulochkin, Semyon Tucha and Sergei Kaysarov—who make a pact to remain unattached to any women until the war ends, no matter how tempting the prospect. However, the circumstances change when Major Vasily Bulochkin is reassigned to the slower, less glamorous
U-2 biplane squadron after an injury renders him unfit to fly high-speed fighters. Bulochkin, accustomed to the speed and agility of fighter aircraft, initially finds his new role with the “night witches,” a squadron consisting entirely of female pilots, both humbling and frustrating. As the men interact with the women of the U-2 squadron, their pledge begins to unravel. Kaysarov is the first to break the pact, revealing that he has secretly been married for three months. When a reporter Valentina "Valya" Petrova from
Pionerskaya Pravda, arrives at the airfield, Bulochkin finds himself drawn to her and soon follows suit, abandoning his vow of bachelorhood. Meanwhile, Tucha strikes up a mutual affection with navigator Ekaterina Kutuzova, a staunch advocate for staying single. Over time, Bulochkin comes to appreciate the unique strengths of the U-2 aircraft, realizing that what he once saw as its weaknesses can be significant advantages in certain situations. He ultimately declines an offer to return to fighter aviation, choosing to remain with the U-2 squadron. By the end of the film, the U-2 is officially renamed the Po-2 in honor of its designer, Nikolai Polikarpov. The three friends each dance with their new partners: Kaysarov with his wife Svetlova, Bulochkin with Valentina, and Tucha with Kutuzova. Tucha even jokes about forming a new kind of “squadron” with Kutuzova—a family unit, neither fully male nor female, but mixed. Valentina introduces Bulochkin and his friends to her father, a general in the air force, who good-naturedly points out the irony of the self-proclaimed bachelors succumbing to romance. The film ends with a celebration of newfound connections and mutual respect among the pilots. ==Facts==
