Heavenly Swallows (Russian: Небесные ласточки, romanized: Nebesnye lastochki) is a 1976 Soviet two-part musical comedy-drama television film directed by Leonid Kvinikhidze, based on the vaudeville-opérette Mam'zelle Nitouche.

Nearby is a monastery with the boarding house "Celestial Swallows", where under the strict eye of nuns girls from noble families learn good manners and etiquette.

Frustrated by unexpected changes in her own life that do not coincide with her dreams, the girl is not willing to sit in her hotel room and decides to visit the theater alone - she knows all the roles, all the musical parties in today's performance.

Meanwhile, a grandiose scandal is springing up in the theater - the starring role of Korina, who previously received Celestin's wooing favorably and dismissed the straightforward officer-like courtship of Major Alfred Château-Gibus, after hearing from one of her gossipy girlfriends during an intermission, that the maestro was seen in a hotel with a young girl, she is furious, demonstratively quarrels with the director and leaves with the major, saying that she will not act "in this mediocre play".

The play is on the verge of a breakdown, but the situation is saved by Denise who appears in the theater (who introduces herself as "Mademoiselle Nitouche"), whom the lieutenant Fernand Shampleret accidentally meets, and takes her behind the scenes.
