It's 1940 and Berlin is paralysed by fear. But following the death of their son on the Nazi front line, a working-class couple begin an extraordinary act of resistance – dropping anonymous postcards all over the city attacking Hitler and his regime.
And so begins the cat-and-mouse period thriller Alone in Berlin. But, despite being based on Hans Fallada's 1947 novel, the story itself is a true one.
It is the story of Otto and Elise Hampel, who are renamed here as Otto and Anna Quangel, and are portrayed by Brendan Gleeson and Emma Thompson.
And it is full of cloak-and-dagger suspense as the Quangels become virtual spies as they look for new ways to deposit their postcards in public while evading capture for their activities.
On June 26, there will be a special advance screening of the powerfully moving true-life drama, attended by special guests, at the Imperial War Museum in London.
There will also be a private viewing of some of the museum's exhibits from Nazi Germany.
This will be followed by a panel discussion exploring "people power", the realities of protest in Germany during the Second World War and how those issues resonate today.
For anyone unable to make it to the London event, it will be broadcast in 100 cinemas across the country.
