What is Atlantic Crossing about?

The eight-part drama follows Norway's Crown Princess Märtha as she is taken under the wing of the US President after being forced to flee to America for safety when her country is invaded by the Nazis during the 1940s.

As the official synopsis from PBS reads: "Her presence in Washington soon influences President Roosevelt's views on the tragic events unfolding in Europe and eventually changes the dynamics of US politics significantly.

"What starts as a friendship turns into affection and turmoil when Märtha speaks out publicly against the Nazi tyranny. In an attempt to fight for her country, she puts her marriage at risk and convinces the President to support Norway - a first step in the struggle that will lead to the US joining the War. However, Märtha's actions cause her to make many enemies, some of them even closer than she thinks: within the walls of the White House."

But, of course, what happened in more private, intimate situations, nobody knows, so we had to imagine what happened behind closed doors."
