怪物史莱克 has become a domesticated family man. Instead of scaring villagers away like he used to, the now-reluctant ogre agrees to autograph pitch forks. Longing for the days when he felt like a "real ogre," 怪物史莱克 is tricked into signing a pact with the smooth-talking dealmaker, Rumpelstiltskin. 怪物史莱克 suddenly finds himself in a twisted, alternate version of Far Far Away, where ogres are hunted, Rumplestiltskin is king and 怪物史莱克 and Fiona (Cameron Diaz) have never met. Now, it's up to 怪物史莱克 to undo all of Rumpelstiltskin's mischief in the hopes of saving his friends, restoring his world and reclaiming his one True 爱情 and family.
