A young woman in a small Czech town sleeps with a musician. When she doesn't hear from him, she packs up and arrives on his doorstep in the big city.

Andula is a young woman who works in a shoe factory on the outskirts of Prague. Although there is an acute shortage of men in the district, Andula does have an admirer, Tonda, but his virtues fall short of the standards set by her incurably romantic ideals. One day the factory manager arranges for the army to bivouac near the town, and a dance is held to celebrate the occasion. The soldiers, however, are mostly middle-aged reservists, and the bored Andula turns her attentions toward Milda, the piano player in the dance band. Following some awkward preliminaries, Andula spends the night in Milda's room and falls in love. The next weekend she spurns Tonda and hitchhikes to Prague. She finds Milda's address and arrives unannounced at his home, where she is met by his bewildered and scandalized parents. At the time, Milda is playing for a dance and pursuing another conquest, and his parents are obliged to permit Andula to sleep on the living room sofa. When Milda finally returns, his outraged mother hustles him off to the family bed for a long--and loud--session of recriminations and moralizing. Andula listens through the door, her teary eyes expressing her disappointment. When Milda insists that he hardly knows her, that he never gave her the slightest encouragement, and that he certainly has not in any way obligated himself to her, she sadly returns to her factory dormitory. With her pride and reputation at stake and her romantic nature refusing to give in, she tells one of her girl friends about the lovely time she had with Milda and his parents at their home in Prague.
