The year is 2163 and the seriously damaged fighter R9 Arrowhead has just returned to Earth from its mission to destroy the Bydo empire. The ship is rescued by the cruiser Croque-Monsieur and transferred to an orbital space station.

One year later, astronomers in Central Asia observe mysterious objects falling from the sky, and shortly after, control of the Moritz-G extermination platform is lost.

This high-tech machine, capable of destroying an entire planet, descends on a city and levels it. Although its weapons have not yet been activated, the advanced defense systems make Moritz-G almost impossible to engage.
