In England in 1910, we meet the troubled Banks family. Young Jane and Michael have sent many a nanny packing before Mary Poppins arrives on their doorstep. Using a combination of magic and common sense, she must teach the family members how to value each other again. Mary takes the children on many magical and memorable adventures, but Jane and Michael aren't the only ones upon whom she has a profound effect, and the grownups may also find themselves transformed by the witty and whimsical nanny.
