During the Blitz of London, Nutbourne Boys School suddenly discovers that due to an administrative error at he Ministry of Education, it has to billet the girls of St. Swithins. The two heads are soon at loggerheads and in despair, particularly Whetherby Pond (Alastair Sim), who spends his first night in a co-ed school sleeping in the bath. When the girls parents visit, and the Nutbourne governors arrive, things go from bad to disastrous. Pond and Miss Whitchurch (Margaret Rutherford), decide to start a school in Tanganyika.
