Cottage to Let

In 1941, 15-year-old Londoner Ronald Mittsby (George Cole) evacuates to a small Scottish village and is placed in the home of inventor John Barrington (Leslie Banks) and his eccentric wife. The nosy Ronald discovers that John is working on a secret weapon. With the arrival of wounded but ominous RAF pilot George Perry (John Mills), quirky boarder Charles Dimble (Alastair Sim) and John's distracted assistant, Ronald is certain that he has uncovered a dastardly spy plot.
