The happily ogred couple of Shrek (Mike Myers) and Princess Fiona (Cameron Diaz) visit Fiona's disapproving parents, King Harold (John Cleese) and Queen Lillian (Julie Andrews), and get assaulted at the palace by an aerial Fairy Godmother (Jennifer Saunders) who has some sort of crooked deal going with the king whereby her son, Prince Charming (Rupert Everett), gets to marry Fiona. Or something like that. Will Shrek and Fiona be tempted into human beauty and give up their natural state of ogretude? Will Donkey (Eddie Murphy) and Puss-in-Boots (Antonio Banderas), a duelling cat, help them retain their honor and beautiful green complexion?
