When a green ogre called Shrek discovers his swamp has been 'swamped' with all sorts of fairytale creatures by the scheming Lord Farquaad, Shrek sets out, with a very loud donkey by his side, to 'persuade' Farquaad to give his swamp back. Instead, a deal is made. Farquaad, who wants to become the King, sends Shrek to rescue Princess Fiona, who is waiting for her one true love. But once they head back with Fiona, it starts to become apparent that not only does Shrek like Fiona, but Fiona is keeping something secret.
