Pirate Queen Lorelei drugs Royal Commodore Arthur at a banquet, steals his treasure map, and accidentally awakens century‑old undead pirate Captain Black Tide. Handcuffed together, they plunge into the sea. Sworn enemies, they survive a deserted island—he takes a bullet and falls off a cliff for her; she uses Poseidon’s Blood to keep him alive for three days. He awakens, tears off his uniform, abandons his title, and becomes her first mate: "My sword only fights for you." The Imperial Admiral colludes with the undead to steal the Eye of Poseidon. The pair dive to the Atlantis Altar, uncover Black Tide's immortality secret. Final showdown: Lorelei summons Leviathan; Arthur drives his blade through Black Tide's heart, ending the curse. On the surface, 20 royal warships block them. Lorelei raises the Eye; Leviathan crushes the fleet. At sunset, she dons her hat, sets the Eye in the wheel, and declares: "We're going to rob the whole world." Arthur kisses her from behind. Two pirate kings sail side by side into the starry sea.
