Once upon a time in a far away swamp, there lived an ornery ogre named Shrek (Mike Myers) whose precious solitude is suddenly shattered by an invasion of annoying fairy-tale characters. There are blind mice in his food, a big, bad wolf in his bed, three little homeless pigs and more, all banished from their kingdom by the evil Lord Farquaad (John Lithgow).
Determined to save their home-not to mention his own-Shrek cuts a deal with Farquaad and sets out to rescue the beautiful Princess Fiona (Cameron Diaz) to be Farquaad's bride. Accompanying him on his mission is a wisecracking Donkey (Eddie Murphy), who will do anything for Shrek?except shut up.
Rescuing the Princess from a fire-breathing dragon may prove the least of their problems when the deep, dark secret she has been keeping is revealed.
