Jack-of-all-trades Bert introduces us to England in 1910. Young Jane and Michael have met their match in nanny Mary Poppins. Using a combination of magic and common sense, Mary Poppins takes the children on many magical and memorable adventures. But Jane and Michael aren't the only ones she has an effect upon. Grown-ups learn a lesson or two from the nanny who advises that "Anything can happen if you let it."
