The plot: Screenwriter Catrin Cole (Gemma Arterton) is asked
by Britain’s Ministry of Information to make a film about two twin sisters who
take their father’s boat out to help in the evacuation of Dunkirk. As she works
closely with writer Tom Buckley (Sam Claflin) and actor Ambrose Hilliard (Bill
Nighy), they put together a film that they hope will meet the Ministry’s wishes
for a production that will bring the nation together. However, as a series of
uncontrollable events and mandates fall their way, up to and including being
forced to include American Carl Lundbeck (Jake Lacy) into the film despite his
lack of acting experience, they’ll have to work hard to make a uniting film
before it tears them all apart.
