Commander Peter Kent of the Royal Navy and his wife May have three children, ranging form five to eleven years: Peter, Anne and Fusty. Kent comes home after three years abroad with no idea how to handle the children. When Mary has to fly to Canada, Peter takes his children to his father's new country home, which turns out to be a windmill. They end up clashing with an American family in the neighborhood.
