A battle of the sexes begins to rage in an isolated private school in this charming British comedy. Just outside of London during World War II, Axis bombing forces the evacuation of a private all-girls school, St. Swithins. Thanks to a bureaucratic mix-up, the girls of St. Swithins and their Headmistress Muriel Whitchurch (Margaret Rutherford) are to be billeted at the nearby Nutborne Boys School. While the students learn to make do with the crowded conditions, Nutborne headmaster Wetherby Pond (Alistair Sim) is less than pleased with the situation, especially after he and Whitchurch begin butting heads over which of them is truly in charge. The Happiest Days Of Your Life was based on a popular stage comedy by playwright John Dighton.
