A blast of wind, a house-rattling bang, and Mary Poppins arrives at Number Seventeen Cherry Tree Lane. Quicker than she can close her umbrella, she takes charge of the Banks children--Jane, Michael, and the twins--and she changes their lives forever.

Mary Poppins is likely the most exciting nanny England, and the world, has ever seen. The Banks family has no idea what's in store for them when she blows in one autumn evening. Soon, the children are having tea on the ceiling, flying around the world in a minute, and secretly watching as their unusual nanny pastes gold paper stars to the sky.
