In the late twentieth century, Admiral Julian 3rd can get no rest, for he knows his future. He will be reborn as his grandson in the next century to journey through space and make an ominous discovery inside the moon; he will live again in the dark years of the twenty-second century as Julian 9th, who refuses to bow down to the victorious Moon Men; and as Julian 20th, the fierce Red Hawk, he will lead humanity's final battle against the alien invaders in the twenty-fifth century.
When humanity reaches the Moon following decades of global war, they unknowingly unleash catastrophe upon Earth. In those first days, humanity basks in peace, and many of the Earth's nations disarm their militaries, paving the way for an invasion by the Kalkars, a vicious lunar race. Under the oppressive heel of Lunarian rule, the societies of Earth are reduced to impoverished ruins.
