In the eagerly-awaited film based on the hit television series, Homer must save the world from a catastrophe he himself created. It all begins with Homer, his new pet pig, and a leaky silo full of droppings - a combination that triggers a disaster the likes of which Springfield has never experienced. As Marge is outraged by Homer's monumental blunder, a vengeful mob descends on the Simpson household. The family makes a narrow escape, but is soon divided by both location and conflict. The Springfield citizenry has every reason to be out for Simpson blood. As the fates of Springfield and the world hang in the balance, Homer embarks on a personal odyssey of redemption - seeking forgiveness from Marge, the reunion of his splintered family, and the salvation of his hometown.
