Taking a set phrase literally, a topic about the romanticism of nighttime in Paris, the film shows a part of the city much talked about but rarely seen as it is. Both the well-known sites and the anonymous streets seem even more beautiful in the darkness and tranquility of the after-hours, inhabited only by the people of the night. A collection of images as touristic postcards, a first-person walk, drifting through the streets of a city heavy-laden with the weight of history and art.
