After a banker's children lose their nanny due to her frustration with them, a change in the wind blows in a magical nanny who matches the children's qualifications, but not those of their very proper father. As Mary Poppins helps the children magically explore the world around them, their father grows increasingly disapproving of her methods, and he must eventually deal with his own distance from his children.

An amateur witch, along with three precocious orphans, flies into one fantastic adventure after another aboard a bewitched bed to save the country from hostile invaders.
