Output: In Victorian England in the 1860s, widowed undertaker Cedric Brown has seven unruly children. He is clumsy and loves his children but since the death of his wife has spent little time with them and cannot handle them. The children have had a series of nannies, whom they have systematically driven out by their bad behaviour. They also take great pleasure in terrorizing their cook, Mrs. Blatherwick. Besides their father, the only one the children will ever listen to is Evangeline, the familys uneducated but sweetnatured scullery maid. One day, Cedric discovers multiple references for a Nanny McPhee throughout the home. That same night during a storm, the children cause havoc in the kitchen at the same time Cedric sees a shadow behind the door and opens it to reveal a frighteningly hideous woman, who states that she is Nanny McPhee and is a government nanny. With discipline and a little magic, she transforms the familys lives. In the process, she changes from ugly to beautiful, her warts and unibrow disappearing and her oversized nose shrinking. The children, led by the eldest son Simon, try to play their tricks on her, but gradually start to respect her and ask her for advice. They change to responsible people helping their clumsy father in solving the family problems, making Nanny McPhee less and less needed. The family is financially supported by Cedrics late wifes domineering and nearsighted aunt Lady Adelaide Stitch, who demands custody over one of the children. She first wants Christianna Chrissie, one of the daughters, but Evangeline volunteers and Adelaide agrees, assuming she is one of the daughters. She also threatens to reduce the family to poverty unless Cedric remarries within the month; the family would lose the house, and they would not be able to stay together. Desperate, Cedric turns to a vile and frequent widow, Mrs. Selma Quickly. The children assume from reading books of fairytales that all stepmothers are terrible women who treat their stepchildren like slaves; therefore they sabotage a visit of Mrs. Quickly, who leaves, angry at Cedric. After the financial rationale for the marriage is explained to the children, they agree to the marriage, and appease Mrs. Quickly by confessing they were to blame for the disturbance of her visit, luring her back to their father with tales of their Great Aunt Adelaides wealth. However, the children soon discover that Mrs. Quickly is just as cruel and awful as any fairytale stepmother when she breaks baby Aggies beloved rattle which previously belonged to their late mother, and was the only thing they had left of her. When everybody is gathered for the marriage ceremony, they disturb the ceremony by pretending there are bees inspired by the way Quickly told them to behave and baby Aggie repeating the word, but pronouncing it as beehive, chasing the guests, and throwing the pastries intended for the banquet at everyone present. Cedric swiftly understands that they dont like the bride and, recognising that he does not like her either, joins in the commotion himself. Mrs. Quickly cancels the marriage and storms off in anger. This seems to mean that Adelaides marriage deadline is missed, but Lily asks Evangeline whether she loves Cedric. She first denies, explaining that it would be inappropriate because of her station as maidservant, but then confirms she does. Cedric, who loves Evangeline back, marries Evangeline then and there, satisfying Aunt Adelaides conditions for maintaining his allowance; and Nanny McPhee who is now beautiful, magically makes it snow, which transforms the wedding scene and changes Evangelines clothes into a beautiful wedding dress, and restores the childrens real mothers rattle for them. Nanny McPhee leaves surreptitiously, in accordance with what she told the children before on her first night: When you need me, but dont want me, then I must stay. When you want me, but no longer need me, then I have to go.
