A soldier is unfrozen after years in cryo, and the only thing he wants is to kill everything in his path. The plot doesn't exist to complicate him, it exists to clear obstacles out of his way so he can fight. It's 1986 asking one pure question: what if you made an action movie about a man with no off switch, no guilt, no character arc, just an appetite for violence that the entire planet becomes responsible for feeding.
On the distant colony world of Jerra, decades of war have left the planet ravaged. Geist is an M.D.S., a Most Dangerous Soldier: an enhanced human with unmatched fighting ability and an endless hunger for combat. He was frozen and sealed inside a satellite because no one could control him. Years later that satellite crashes, and Geist rises to fight again, this time alongside the army as it tries to keep the planet's central computer from launching a doomsday program that would wipe out all life on Jerra. The result is a one-episode 1980s mecha OVA full of science fiction action.
