When a kind-hearted old woman's pet pigs become sick, she creates a special medicine using a secret family recipe passed down for generations. The potion accidentally causes the pigs to grow to an enormous size, and they escape from the woman's backyard. The giant pigs cause hilarious chaos throughout the town, inadvertently helping people with their problems, such as scaring away bullies and demolishing old buildings that need to be torn down. The old woman and the townspeople must work together to find a way to shrink the pigs back to normal size while also learning to appreciate the unexpected benefits of the situation.
