Shrek, a mean and highly territorial green ogre who loves the solitude of his swamp, finds his life interrupted when countless fairytale creatures are exiled there by the fairytale-hating and vertically-challenged Lord Farquaad of Duloc. An angered Shrek decides to ask Farquaad to exile them elsewhere. He brings along a talking Donkey, who is the only fairytale creature willing to guide him to Duloc.
Back in Far Far Away, Shrek and Fiona share news of their marriage. But a sinister plan involving Prince Charming threatens their "happily ever after."
