Perseus, a demigod, descends into the Underworld to strike a deal with Hades in order to resurrect his murdered lover and mother. But step by step, he is drawn into a treacherous web of divine conspiracy. After sacrificing all his divine power to bring his loved ones back, he is reduced to a mere mortal—yet it is as a mortal that he overthrows a tyrant and claims a throne. Caught between prophecy and destiny, Perseus chooses to reject eternal life and godhood. All he desires is to protect the mortal world and the home he cherishes, as an ordinary man. But when darkness stirs once more, a new legend is just beginning to unfold.
