pirates dead man plot2

Will, Jack, and a few crew members escape their captors, unexpectedly recruiting Pintel and Ragetti along the way, and head for sea. Will learns that Jack has been searching for a particular key. He agrees to give Will the compass if he helps him find the key and the object it unlocks. Seeking assistance from Tia Dalma, an obeah priestess, Jack learns the compass fails to work because he does not know what he truly wants. The key, Tia tells him, unlocks the Dead Man's Chest containing Davy Jones' still-beating heart—to avoid lost love's pain, Jones carved the heart from his chest and buried it. Whoever possesses the heart controls Davy Jones, thereby controlling the world's oceans. Back at sea, the Flying Dutchman encounters Sparrow, who deviously attempts to barter Will in exchange for himself. Jones demands 100 souls within three days in exchange for Jack's freedom and keeps Will as a "good faith payment," leaving Jack only 99 more souls to harvest.
In Port Royal, Governor Weatherby Swann frees Elizabeth. Confronting Beckett at gunpoint, she forces him to validate a Letter of Marque—a royal document with which Beckett intends to recruit Sparrow as a privateer, and which Elizabeth wants for Will. Posing as a cabin boy on a merchant vessel, Elizabeth lands in Tortuga where she finds Jack and Gibbs desperately recruiting unsuspecting sailors in a pub to pay off his blood debt. A disheveled Norrington also applies. Blaming Sparrow for his ruin, he tries to shoot him and ignites an angry brawl, but Elizabeth knocks Norrington out and saves Spar2ow. At the pier, Jack reveals the compass' secret to Elizabeth; it points to what the holder wants most in the world. When he convinces her that she can save Will by finding the chest, she gets a bearing. Once the ship is underway, however, an attraction arises between Jack and Elizabeth.
On Isla Cruces, Jack, Norrington, and Elizabeth find the Dead Man's Chest. Will, who has escaped the Flying Dutchman with help from his father, Bootstrap Bill, arrives with the key he stole from Davy Jones. Will wants to stab the heart to free his father, but Jack fears the Kraken will continue hunting him even if Jones is dead, while Norrington desires the heart to bargain back his naval career. As a three-way swordfight erupts, the arrival of Jones' crew and Pintel and Ragetti's attempt to make off with the chest complicate matters even more. Norrington ultimately escapes with the heart and the Letters of Marque while Jones' crewmembers retrieve the now-empty Dead Man's Chest.
