Picking up where the first movie left off, Will Turner and Elizabeth Swan are to be married. However this is interrupted when both are arrested for aiding in the notorious Captain Jack Sparrow's escape. The new captain, Beckett, will lift all charges, if Will can hunt down Jack and bring him back to Beckett, along with his magic compass. However, Jack has other problems. Years ago, he made a deal with Davy Jones to raise the Black Pearl. Time is up. His part of the deal was to give Davy Jones his soul. Once Will finds Jack, unaware of the current situation, Jack coaxes Will into boarding Davy Jones's ship, the Flying Dutchman, and retrieve a mysterious key. This key opens the chest that contains Davy Jones's secret. With it, you can control Davy Jones and his fearsome beast, The Kraken. Once Will retrieves said key, Davy Jones is hot on his trail, now hunting down both Jack and Will. It is now, only a matter of time, before something happens. Hopefully the pirates can reach the chest and stop Davy Jones, before he reaches them and sends them all to a watery grave.
As they are getting married, Swashbuckling former blacksmith Will Turner and Elizabeth Swan, daughter of Governor Weatherby Swann are both arrested by Lord Cutler Beckett and are sentenced to death. Beckett makes a deal with Will for his freedom, Beckett wants Will to find his old friend, pirate Captain Jack Sparrow and give him Jack's magic compass. Agreeing, Will tracks down Jack and finds him and his crew of The Black Pearl on a tribal island inhabited by cannibalistic tribal warriors. Jack makes a deal with Will and he will only give Will his compass, if Will agrees to help him find a key to a chest containing the heart of the octopus like Davy Jones, captain of The Flying Dutchman, so he may free his soul from eternal servitude. Pursued by Davy Jones and his crew of undead warriors and his creature that lives in the sea "The Kraken", Will and Elizabeth go in aid of Jack as they set out to get to the chest first before Davy Jones does, which could spell doom for Jack and his companions and Will must succeed in giving Lord Beckett, the compass, as Beckett plots to put a end to the pirates forever.
