Angemacht (1980)

A lonely young lady strolls through the busy streets of a big city in the evening and casts meaningful glances at passers-by. Short conversations ensue and a man finally invites her to his place. He laboriously prepares dinner for her, but she becomes increasingly bored and suddenly disappears. She walks through the streets again and finally enters a record store. With ambiguous words she attracts the attention of the salesman, then the movie ends.
