George Banks is busy in his bank work while Winifred is busy in her Women's rights activities and both of them almost never dedicate (to be strongly into something and giving a lot of time for that) time for their children but instead keep them with different nannies. When one of the nannies named Katie quits the job, Mr. Banks begins to search for a different nanny. At night, the children write their father a letter that describes the kind of nanny they want, but he then rips the letter and throws it into the fire and writes for himself the kind of nanny that he wants, someone that is serious and arranged.
