The main characters include Edith Heap, an Intelligence plotter at RAF Debden; Richard, a firefighter; Joan, who has a romantic affair with her neighbour Rupert; Eric Brady, a London evacuee, and his sister Kitty; and Marie Price, a Liverpudlian local. Their personal experiences and perspectives are used to stitch the narrative together through first-hand accounts and archival footage.

The film follows Eric Brady, a London evacuee, and his sister Kitty, showing Eric's experience moving to Coventry and the class divide and clashes with local children there. However, the documentary does not explore the broader historical context of evacuation plans, such as the intended overseas evacuations to Canada, America, and New Zealand, or the tragedy of a ship sinking that killed 260 people.

Joan details a romantic affair with her neighbour Rupert, which is one of the personal stories interwoven with the archival footage and first-hand accounts. This subplot adds a human and emotional dimension to the depiction of life during the Blitz.

The Communist Party is briefly shown as plucky underdogs trying to undermine the government. However, the film omits the important historical detail that the Communist Party only supported the war effort after Russia was invaded, which affects the accuracy of this portrayal.

Yes, one noted inaccuracy is the use of an American train horn sound during the evacuee scenes instead of the authentic sharp whistle of British steam trains of the time. Additionally, the film's narrow scope and omission of broader historical context around characters' stories, such as evacuation plans and political affiliations, are considered missed opportunities for depth.
