This short fiction film tells the story of a very unusual satellite named Zenon. Zenon is a product of the most up-to-date technology and so displays an unusual characteristic for a computer: he is conscious! Orbiting the Earth, he is in constant contact with Estelle, who is in charge of a major, planet-wide research project on water. Faced with the disturbing situation he observes, Zenon soon becomes bitter and disillusioned--to the point where he substantially alters his mission. Could Zenon's creator, the mysterious Professor Nguyen, have foretold how the mission would turn out? The story continues in the film Deserter.
