Pirates - On Stranger Tides

Pirates of the Caribbean: On Stranger Tides is a 2011 adventure fantasy film and the fourth installment in the Pirates of the Caribbean series. Gore Verbinski, who had directed the three previous films, was replaced by Rob Marshall, while Jerry Bruckheimer again served as producer.

Plot:-
After a failed attempt to rescue his former first mate, Joshamee Gibbs, (Kevin McNally), Captain Jack Sparrow (Johnny Depp) is brought before King George II (Richard Griffiths) in London, who wants Jack to guide an expedition to the Fountain of Youth before the Spanish locate it. Heading the expedition is Jack's old nemesis, Captain Hector Barbossa (Geoffrey Rush), now a privateer in service to the Royal Navy after losing his leg and ship, the Black Pearl.

Jack escapes, but his father, Captain Teague (Keith Richards), finds him and warns Jack about the Fountain's tests. He also reveals that someone is impersonating Jack. The impostor is Angelica (Penélope Cruz), Jack's former lover and daughter of the ruthless pirate Blackbeard (Ian McShane), who practices voodoo magic and, with his sword, possesses supernatural powers.

Jack is taken aboard Blackbeard's ship, the Queen Anne's Revenge, and forced to lead the way to the Fountain and find two silver chalices that once belonged to Juan Ponce de León, both of which are believed to be aboard his lost ship. The Fountain's water must be drunk simultaneously from the two chalices. The person drinking from the chalice containing a mermaid's tear has their life extended, while the other dies, their life drained from their body. Meanwhile, Gibbs, having memorized and destroyed Jack's map, barters with Barbossa to guide him to the Fountain.

Blackbeard wants the Fountain's power to circumvent his predestined fatal encounter with "a one-legged man" and sets a course for Whitecap Bay, where they are attacked by a vicious horde of mermaids. Blackbeard manages to capture a mermaid (Àstrid Bergès-Frisbey) with whom Philip Swift (Sam Claflin), a captive missionary, falls in love and names Syrena. Blackbeard then sends Jack to retrieve the chalices from de León's ship.

When Jack finds the grounded, decaying vessel, Barbossa is waiting inside and the Spanish in possession of the chalices. However, Barbossa only seeks revenge against Blackbeard for capturing the Black Pearl, which forced Barbossa to amputate his own leg to escape. He and Jack join forces to defeat Blackbeard, before heading to the nearby Spanish camp to steal the chalices. Meanwhile, Syrena, reciprocating Philip's love, is tricked into shedding a tear which Blackbeard collects leaving her to die. He forces Philip to go with him. Jack returns with the chalices and Gibbs, with whom he had reunited while assisting Barbossa. Jack and Blackbeard compromise for the return of Jack's confiscated magical compass and Gibbs' relase. In return, he vows to give Blackbeard the chalices and lead him to the Fountain; Blackbeard agrees and Gibbs departs with Jack's compass.
At the Fountain, Blackbeard and his crew are attacked by Barbossa, and then by the Spanish, who were sent by their king to destroy the Fountain, as he believes its power is an abomination against God. A battle ensues, which culminates in Barbossa stabbing Blackbeard with a poison-laced sword. Angelica accidentally cuts herself while removing it from Blackbeard. Barbossa claims the sword and assumes command, leaving with Blackbeard's crew. Meanwhile, Philip, though mortally wounded, escapes and returns to free Syrena. After finding the chalices that the Spaniard had tossed into deep water, Syrena gives them to Jack, then retrieves the dying Philip, taking him underwater to save his life.
As Blackbeard and Angelica lay dying, Jack arrives with the two chalices; Angelica agrees to sacrifice herself for Blackbeard but Jack tricks Blackbeard into drinking the wrong chalice and gives Angelica the tear, extending her life whilst Blackbeard dies. Despite declaring their love, Jack, knowing Angelica may want to avenge her father's death, strands her on an island, intending for a passing ship to pick her up. Meanwhile, Barbossa, who now commands the Queen Anne's Revenge, renounces his ties to the crown and reverts to piracy. Jack finds Gibbs, who used Jack's compass to locate the Revenge and retrieve the Black Pearl, as well as other captured ships that Blackbeard had magically shrunk and bottled. The two head off, hoping to find a way to return the Pearl to her original size.

In a post-credits scene, Angelica, still on the island, finds Blackbeard's voodoo doll of Jack, which has washed ashore.
