"While most of the city sleeps, much activity continues to go on. Among the "night people," there is a special camaraderie and happy spirit, which grows out of an awareness that theirs is a special kind of work. Without narration, this film joyfully explores the city at night with special emphasis on the people and their occupations. A unique sound track is created by human voices which imitate the myriad sounds of the night people at work." - Summary from the teacher's guide.
