Blart is not an average boy. He lives on a pig farm with his grandfather and doesn't care about being heroic or famous or legendary, but he does know that if you want to catch a pig you have to sneak up behind it and take it by surprise.

So when a great wizard visits and explains that humankind depends on Blart joining his quest, Blart says no - until the wizard threatens his pigs.

Reluctantly, Blart embarks on a very epic quest stuffed with brilliant characters: a feisty princess who likes dragons, a warrior who's a big softie at heart, a disaffected dwarf, and evil Zorab, trapped in a mountain, waiting for his minions to dig him out.
