In the distant future, humanity has colonized other planets across the universe. While many worlds enjoy peace, the planet Jerra has been devastated by decades of war. Geist is an M.D.S. (Most Dangerous Soldier), an enhanced human possessing unmatched combat skills and an insatiable thirst for battle. Due to his uncontrollable nature, Geist is cryogenically frozen and confined within a satellite. Several years later, the satellite crashes, and Geist awakens from his slumber to join another war. This time, he aids the army in stopping the planet's central computer from activating a doomsday device that would result in the total annihilation of all life on Jerra.
