The story takes place in the 17th century, in the Caribbean Sea, where pirates are said to be most active. The funny and charming Jack Sparrow (Johnny Depp) is a pirate active in the Caribbean Sea and owns his own pirate ship, the "Black Pearl". For him, the most comfortable life is to drive the "Black Pearl" and wander around the Caribbean Sea, robbing passing ships freely. But unfortunately, his enemy, the wily Captain Barbarossa (Geoffrey Rush) stole his "Black Pearl". Barbossa is a villain who does all kinds of evil. After he robbed Jack's "Black Pearl", he became more rampant and rampant in the Caribbean Sea, becoming the overlord of the entire Caribbean Sea for a while. Once, Barbossa and his gang attacked the small town of Port Royal and kidnapped the Governor's daughter Elizabeth Swann (Keira Knightley) and Elizabeth's childhood sweetheart, the blacksmith apprentice Will Turner (Orlando Bloom). They tried every means to rescue Captain Jack from prison and stole the fastest warship "Interceptor" of the British Royal Fleet to quickly chase the "Black Pearl". During the fight, Will and Jack discovered that Barbarossa and his pirates were carrying a spell, and on every moonlit night, they turned into undead skeletons, and Elizabeth was the key to unlocking the spell.
