Would've thought wartime London, despite daily bombings and innumerable tragedies, large scale and small, could provide such amusement? Catrin, seconded to the Ministry of Information (dis-information?), increasingly realises messages are lost if they don't entertain. Then there is Dunkirk .. how can such disaster entertain? Lissa Evans convinces us that this IS what it was like ... even if, like her film of the Starling sisters' heroic deeds at Dunkirk, it bears little relation to a 'real life' account. There is a deeper truth in their daring, Catrin realises, just as the film reveals and reflects wider truths of the war situation. Evan's characters, dialogue, and recreated adverts and propaganda scripts are convincing, touching, funny and sad in turn..from witty hoot to heart wrench at the sound of a siren.
