In Mary Poppins Comes Back, the beloved nanny returns when she's pulled down from the clouds by the string of Michael's kite. In her care, the Banks children meet the King of the Castle and the Dirty Rascal, visit the upside-down world of Mr. Turvy and his bride, Miss Topsy, and spend a breathless afternoon above the park, dangling from a clutch of balloons. Surprises are sure to pop up when Mary Poppins is around!
