2098. Mankind has left the Earth and is now living in space colonies. Ludwig, a research robot from a faraway civilisation and his spaceship are looking for forms of new energy. Unfortunately, mankind´s new space colonies are not listed on his interstellar maps, which results in a fatefull crash with the physis, the biggest station with a billion inhabitants. The crash does not only tear a huge hole into the physis´ protective cover, but also damages Ludwig´s spaceship badly enough for him to lose control of it and crashland on planet Earth. Now it´s a race against time.
