The upper image in this film is a single shot underneath a road bridge where it crosses over a river. The images in the lower sequence are close-up shots of the surface of the water under the bridge. They are arranged in no particular order, and their appearance may be reminiscent of abstract paintings.

The film explores the idea of invisible images in landscape which the British painter Paul Nash wrote about in a Country Life magazine article in May 1938: “The landscapes I have in mind are not part of the unseen world in the psychic sense, nor are they part of the Unconscious. They belong to the world that lies, visibly, about us. They are unseen merely because they are not perceived; only in that way can they be regarded as invisible.”
