In Shrek 2, Shrek and Princess Fiona are married now and her parents have a problem accepting the ogre as a son-in-law.
The big green guy is back, off on a journey with Fiona and Donkey to visit his in-laws. But getting there is half the fun - he takes on a potion-making fairy, a snarky prince and an ogre hunter named Puss in Boots.
