Amid turmoil, Princess Selena journeys to the Holy Land for coronation. Achilles, God of War, escorts her to honor an old friend. Vain Lila betrays him to Rose Knight Leia, while others scorn Achilles in humble disguise. Attacks by the Black Knight and a serpent-mage ensue; Achilles reveals divine power, saves poisoned Selena by sucking out venom, and they fall in love. Jealous Lila sets a trap, but falls to her death with Leia and others. At the sacred site, Prime Minister Solomon unleashes an underworld curse and undead army. Achilles shatters the Gates of Hell, sacrificing himself to end the calamity. Selena is crowned, and Achilles returns—they stand together to protect the newborn kingdom.
