Driven by a relentless desire to break the centuries-old curse binding his father, Will Turner, to the
Flying Dutchman, a determined young sailor named Henry Turner resolves to find the legendary Trident of Poseidon. Knowing this
mythical artifact possesses absolute control over the seas, Henry desperately seeks the help of the notorious Captain Jack Sparrow. However, Jack is currently hitting rock bottom—broke, perpetually drunk, and abandoned by a disgruntled crew who have grown weary of his endless string of failed heists and disastrous misfortunes.Simultaneously, a brilliant and fiercely independent astronomer named Carina Smyth is sentenced to death for witchcraft because she studies horology and the stars. She holds a vital clue to finding the Trident: a red diary left behind by the father she never knew. Henry crosses paths with Carina, and after a narrow escape from execution, the two form an uneasy alliance. They soon cross paths with Jack Sparrow, whose latest misadventure involving a bank vault heist has left him even more destitute.The trio is relentlessly hunted across the Caribbean by a terrifying new enemy: Captain Armando Salazar, a ghostly Spanish ship captain consumed by an obsessive hatred for Jack. Years ago, a young Jack lured Salazar’s ship into the deadly Devil’s Triangle, destroying the vessel and trapping Salazar’s crew in a cursed, undead limbo. Freed by Jack trading his magical compass for a bottle of rum, Salazar and his crew of spectral sailors are now cutting a bloody swath of vengeance across the ocean, slaughtering anyone who stands in their path.To survive the impending onslaught, Jack, Henry, and Carina form an alliance with Captain Hector Barbossa, who possesses the power of Blackbeard's sword. Barbossa strikes a deal with Salazar to lead them to Jack, but secretly plots his own survival. After a series of thrilling naval battles, betrayals, and narrow escapes, the group finally locates the island housing the Trident of Poseidon, which is miraculously revealed only through the solving of Carina’s star-chart diary.A fierce climactic battle erupts on the ocean floor as the parted sea threatens to crush them all. Salazar attacks Jack, seeking his final vengeance, but Henry manages to shatter the Trident. The destruction of the artifact instantly breaks every curse of the sea, restoring Salazar and his crew to mortal flesh—only for them to be immediately drowned by the collapsing ocean walls. In the chaotic rescue, Barbossa sacrifices his life to save his long-lost daughter, Carina, redeeming his villainous past. With the curses lifted, Henry and Will Turner are joyfully reunited, and Jack Sparrow proudly sails away into the horizon aboard the beloved Black Pearl.
