Plot Summary:

Homer Simpson is used to alienating people, but nothing compares to the level of animosity he's inspired with his most recent foul-up: polluting Lake Springfield with pig manure he's been storing in a silo. Now, Homer's been fired and the citizens of Springfield quarantined in this first-ever big-screen outing for Matt Groening's animated clan. Dan Castellaneta, Julie Kavner, Nancy Cartwright and Yeardley Smith voice the Simpson family.
