Nanny McPhee and The Big Bang

Nanny McPhee arrives at the door of a young mother, Mrs. Isabel Green, who is trying to run the farm while her husband is at war. After her arrival, Nanny McPhee discovers that Mrs. Green's children are fighting their own battle against two spoiled cousins who have just arrived from the city and have no intention of leaving.

Using everything from a flying motorcycle and a living statue to a tree-climbing piglet and a baby elephant that appears in the most unexpected places, the magical nanny gives five lessons to the mischievous and adventurous children.
