During World War Two, a group of English troops become cut off from their batallion while behind enemy lines in the western desert. Attacked by a German fighter plane and then caught in a sandstorm, the nine men seek refuge in a deserted tomb. However, they soon cross swords with a group of Italian soldiers in a similar situation. While the Italians lay siege to the British unit, the men plan a night-time counter-attack, but it can only be a matter of time before one side buckles under the strain...

Lauded 1936 documentary, showing the various stages and procedures of the operation of the Royal Mail train delivery service, that remains one of the most instantly recognised films in British film history.

It begins with a voiceover commentary describing how the mail is collected for transit. Then, as the train proceeds along the course of its journey, we are shown the various regional railway stations at which it collects and deposits its cargo. Inside the train the process of sorting takes place.

As it nears its destination there is a sequence - the best known in the film - in which WH Auden's spoken verse and Benjamin Britten's music are combined over montage images of racing train wheels.
