The year is 1942 and Britain’s wartime Prime Minister is at the White House for a summit with the President of the United States to discuss the progress of the war against Nazi Germany.

Tobruk has just fallen to Germans and Italian troops and Winston Churchill is desperate to retain the support of the American public, many of who are suspicious of their country’s recent intervention in the old world’s quarrels.

But he also has a pressing personal matter on his mind.

At the same time as leading Britain in the war in Africa and Europe, and trying to emphasise the need for the US to stand shoulder to shoulder with this country in the face of totalitarian dictatorship, Churchill is trying to arrange for the return to the UK of an old acquaintance, the beautiful and glamorous London socialite Doris Castlerosse.
