The headmaster of a boys' boarding school receives word that he must share his campus with the pupils and staff of another institution that has been evacuated due to the Blitz. He is horrified to learn that the new arrivals are from a girls' school, and finds himself perpetually at odds with their indomitable headmistress. Comedy, starring Alastair Sim and Margaret Rutherford.

Nutbourne College, an old established, all-boys, boarding school is told that another school is to be billeted with due to wartime restrictions. The shock is that it's an all-girls school that has been sent. The two head teachers are soon battling for the upper hand with each other and the Ministry. But a crisis (or two) forces them to work together.
