When Angels Fall (1959)

The twenty-one-minute-film is set in a men's public rest room and recounts the day to day existence of an elderly woman who serves as an attendant in the lavatory. As an endless procession of men pass before her, relieving themselves in the urinals, the attendant escapes her reality by daydreaming about the past and the soldier she once loved and the child she bore him.

Unfortunately the movie When Angels Fall is not yet available on HBO Max.
