Mercy Watson loves nothing more than a breezy ride in the Watsons' convertible. It takes a lot of coaxing and a few sweet promises to get the portly pig out of the driver's seat, but she simply adores the wind tickling her ears and the warm sun on her snout. But one sunny Saturday, their peaceful motoring ritual takes a wild and unexpected turn. When their elderly neighbor, Baby Lincoln, suddenly pops up in the backseat looking for a little folly and adventure, everything goes topsy-turvy! In the hilarious confusion, an exuberant Mercy ends up right where she always wanted to be: behind the wheel! With a policeman hot on their tail and a frantic struggle for the brakes, you are in for a blissfully airborne, laugh-out-loud joyride. Buckle up for a high-speed adventure that only a giant helping of buttered toast can fix!
