A magical English nanny, Mary Poppins, arrives at the home of Mr. and Mrs. George Banks, facing the park at No. 17, Cherry Tree Lane in London, to the delight of their young children, Jane and Michael. The proper English father is too preoccupied with his responsibility at the bank. The mother, an ardent suffragette, is not really aware that their two children, left in the care of one nanny after another, are unhappy and unable to communicate with the parents they truly love. Mary Poppins has come to change all this. She settles into the house and soon has everyone wrapped around her little finger. Mary, along with her friend Bert and a host of chimney sweeps, teaches the children how to have fun, and in so doing makes the Banks household a happier place. By the time she opens her umbrella and flies off on a beautiful spring evening, the family is united together in the park, flying a kite.
