The film observes the life of a pipeline in the Czech city of Ústí nad Labem, which forms a network moving through the city like a snake, hissing and waving. It connects all the animals and people in its surroundings. Sometimes it dominates the vague terrain that escapes our conscious attention, sometimes it hides among the trees where it is not visible at all. This industrial snake has no beginning and no end. Its endlessness or circularity points to the daily cycle of life.
