@@http://en.wikipedia.org/wiki/Shrek_2@@When Shrek (voiced by Mike Myers) and Fiona (voiced by Cameron Diaz) come back from their honeymoon, they find an invitation to a royal ball with Fiona's parents to celebrate their marriage, an event Shrek is reluctant to participate in. Fiona talks him into it, and along with Donkey (voiced by Eddie Murphy), they travel to the kingdom of Far Far Away. They meet Fiona's parents, King Harold and Queen Lillian (voiced by John Cleese and Julie Andrews), who are surprised and repulsed by Fiona's choice of husband (particularly the King himself), since they had arranged that Prince Charming rescue her from the castle but now they see that her husband is an ogre.
At a shared meal, Shrek and Harold get into a heated argument over how Shrek and Fiona will raise their family, and Fiona, disgusted at Shrek and her father's behavior, locks herself away in her room that evening, where she meets her Fairy Godmother (voiced by Jennifer Saunders), who is also surprised at Fiona's new looks. Shrek worries that he has lost his true love, particularly after finding her childhood diary and reading that she was once infatuated with Prince Charming (voiced by Rupert Everett).
King Harold is accosted by the Fairy Godmother and Charming, her son. The two retell the Prince's adventures and how he overcame many obstacles and climbed a high tower in order to rescue Fiona, finding instead a cross-dressing wolf. They reprimand Harold for breaking an old promise that Charming would be able to marry Fiona and demand that he find a way to get rid of Shrek. After Shrek reads Fiona's diary and pages containing the single phrase "Mrs. Fiona Charming", Harold arranges for Shrek and Donkey to join him on a fictitious hunting trip, which really is a trap to lure the two into the hands of an assassin, Puss in Boots (voiced by Antonio Banderas).
When Fiona realizes that Shrek left, she asks her father for help, but he replies that he always wanted the best for her and that she should better think about what is the best for her, too. Puss is unable to defeat Shrek and, revealing that he was paid by Harold, asks to come along as a way to make amends. The three sneak into the Fairy Godmother's potion factory and steal a "Happily Ever After" potion that Shrek believes will restore Fiona's love for him.
Shrek and Donkey both drink the potion, but it appears as if it didn't work. When it starts to rain, they leave, and in doing so, fail to notice that the mushroom, which Shrek previously sneezed potion on, changes into a beautiful rose. They wait out the storm in a barn and, while there, Shrek and Donkey fall over and into a deep sleep for no apparent reason. When they awake, they discover the potion's effects were only delayed: Shrek is now a handsome human, while Donkey has turned into a stallion. In order to make the change permanent, Shrek must kiss Fiona by midnight. He, Donkey, and Puss return to the castle to discover that the potion has also transformed Fiona back into her former, human self. However, the Fairy Godmother, having learned of the potion's theft, intercepts Shrek and sends Charming to pose as him and win her love. At the Fairy Godmother's urging, Shrek leaves the castle, believing that the best way to make Fiona happy is to let her go.
To ensure that Fiona falls in love with Charming, the Fairy Godmother gives Harold a love potion to put into Fiona's tea. But Harold replies that it's not possible to make his daughter fall in love in this way. This exchange is overheard by Shrek, Donkey, and Puss, who are soon arrested by the royal guards and thrown into a dungeon, in a parody of COPS. When the royal ball begins, several of Shrek's friends band together to free the trio and create a gigantic gingerbread man (whose name is Mongo), which breaks through the castle's defenses so Shrek can stop Charming from kissing Fiona, but Mongo is presumably killed when his arms break and he falls into the moat with Gingy devastated. Shrek finds he is too late to stop them; instead of falling in love with Charming, though, Fiona knocks him out with a headbutt. It turns out that Harold never gave Fiona the love potion, having realised her love for Shrek, whereupon the Fairy Godmother attacks Shrek. In the ensuing melee, a spell from her wand, presumably to kill Shrek, rebounds off Harold's armor, when he commits self-sacrifice to save Shrek, and disintegrates the Fairy Godmother; it also returns Harold to his true form, that of the Frog Prince. Lilian had been the princess who kissed him and turned him into a human.
As the clock strikes midnight, Shrek and Fiona let the potion's effects wear off and they revert to their ogre selves, while Donkey changes back as well. Harold gives his blessing to the marriage and apologizes for his earlier behavior; the party resumes and the credits begin as they sing (along with Mongo)"Livin' La Vida Loca". After part of the credits, a bonus scene shows that Shrek, Fiona and Donkey are still partying in the night. Dragon, who Donkey has had a romance with, arrives with some of her and Donkey's new children called the "Dronkeys".
