From Wikipedia: Shrek 2's storyline follows a similar plot to that of the film. Shrek and Fiona are on a journey to the Kingdom of Far Far Away to visit Fiona's parents. Shrek's in-laws are not happy that a crude ogre is married to their daughter Fiona and the battle for acceptance ensues. The game covers things not shown in the film. Plot elements are delivered primarily through a storybook interface (text and illustrations) shown before each level.
