Will Hay plays Professor Davis, the intrepid head of a correspondence college, in this wartime comedy. Davis gets wind of the fact that a Nazi spy has infiltrated an economic delegation with the intent of undermining attempts to reach a trade agreement between Great Britain and certain South American countries. The effort to expose the dastardly fellow sees Hay adopt various disguises in a steady onslaught of mistaken-identity comedy.

Laurence Olivier directs and stars in this classic adaptation of Shakespeare's play about the king who led England to victory in the Battle of Agincourt. The film pays tribute to its origins by opening in a version of the Globe Theatre in 17th century London, where Henry (Olivier) takes to the stage along with a variety of nobles to discuss his plans to stake a claim to the French throne. As the range of Henry's ambitions make themselves known, the theatrical artifice gives way to a more naturalised style and follows Henry as he sets sail from Southampton with his army. Inspired by Henry, the invading English hand the French several defeats, culminating in a triumph against far superior numbers at Agincourt. Shot during WWII, the film was designed to raise morale in the ongoing battle against Nazi Germany and earned Olivier an Academy Award for his 'outstanding achievement' in bringing the film to screen.
