In a coastal village ravaged by storms, a deranged prophet known only as the Madman speaks of treasures beneath the sea and curses upon the wicked. When Captain Elias Vane—a disgraced pirate hunted by the Crown—crash-lands ashore, an uneasy bond forms between them. The Madman claims to know the location of a legendary lost fleet, but his visions blur truth and madness. Pursued by naval warships and rival buccaneers, the unlikely pair must sail toward the forbidden Devil's Triangle, where prophecies grow darker. Some secrets, the sea keeps forever. Some madness, saves lives.
