After an unexplainable anomaly creates a tear in the space-time continuum and jumps the entire galaxy and the multiple dimensions into one, a deadly invasion ensues on Earth by an armada known as The Coalition. Quick the respond to the invasion, the world continents unite to create the United World Army, recruiting every able-bodied man they could to fight, including the likes of KC Blackstone, a former soldier in 1952 to fight off the invaders; only to have his arms and legs completely destroyed in an explosion. On the brink of death, his childhood friend and long lost love of his life, Celeste, returns to him after being missing for decades and puts him into stasis until he is awakened 75 years later by a young and rowdy, tomboy genius named Riley, who replaced his missing limbs with new, robotic replacements in the now authoritarian, Coalition occupied Earth. Butting heads at first, KC and Riley are captured by Coalition forces where they are imprisoned in a labor camp when KC finds Celeste to be working for The Coalition. Reluctant at first, he convinces Riley to join him in escaping the labor camp and set off into the stars to save Celeste, and free her from the grasps of The Coalition's powerful overlord, Maxim Drake, and revert the galaxy to how it once was.
