Told over a few short weeks in 1940, the plot follows Pilot Officer 'Septic' Baird (John Gregson) as a fledgling Hurricane pilot posted to an operational squadron during the Battle of Britain. 'Septic' struggles stoically in the face of his boisterous comrades, an earnest would-be girlfriend and impossible numbers of enemy raiders. The Station Commander (Jack Hawkins) puts a human face on the RAF hierarchy, burdened by the knowledge that the fate of the nation really does depend on the skill of his young pilots. 'The few' eventually grasp victory but it doesn't come cheap.

Admittedly wooden by today's standards but, through films like this, a whole generation built up their Saturday afternoon understanding of the RAF's 'finest hour'.
