Seven Days in a Week (1965)

Seven days, or rather evenings and nights, in the life of Jenka (Stanislava Bartosová), a young good-looking nurse. Jenka is attractive to men and enjoys their company, but there is a limit beyond which she won't go, since she is faithful to her Filip, who is doing his military service. On Sunday the girl awaits Filip to arrive on a short period of leave, but instead his friend Míla (Frantisek Nemec) turns up and apologizes for Filip, who has to stay in the barracks.
