Elizabeth Swann (KEIRA KNIGHTLEY) is a young woman who's been enamored with pirates ever since she found a gold medallion adorned with a pirate emblem on a young boy who was rescued at sea. Now many years later, Will Turner (ORLANDO BLOOM) works as a blacksmith and delivers a new ceremonial sword to her father, Governor Weatherby Swann (JONATHAN PRYCE), so that he can give it to Commodore Norrington (JACK DAVENPORT) for his recent promotion.
Norrington publicly has his sights set on Elizabeth, while Will keeps his love for her secret. Their fondness for her is interrupted, however, by the arrival of Captain Jack Sparrow (JOHNNY DEPP). An opportunistic and unorthodox pirate, Jack wants to commandeer a ship so that he can get his revenge on his former first mate, Barbossa (GEOFFREY RUSH).
He led a mutiny against Jack and took command of his ship, the Black Pearl, but then ran across an eternal curse that left him and the rest of the crew in the state of being undead. Whenever struck by moonlight, they turn into living skeletons and have been searching long and hard for the one last gold medallion that will lift the curse.
They soon kidnap Elizabeth and set sail again, causing Will and Jack to form an unlikely alliance. Upon assembling a ragtag crew including the likes of Joshamee Gibbs (KEVIN R. McNALLY), Jack and Will head off to rescue Elizabeth and return control of the Black Pearl to Jack.
