Longing for the days when he was a "real ogre," Shrek (Mike Myers) signs a deal with Rumpelstiltskin that turns his world upside down in the process. Donkey (Eddie Murphy) suddenly can't remember his best friend; Fiona (Cameron Diaz) is now a tough warrior princess; and Puss in Boots (Antonio Banderas) is one very fat cat! Together, they have 24 hours to restore happily FOREVER after.
