Crown Princess Märtha and Crown Prince Olav must flee when Germany attacks Norway. With the Nazis on their heels, they have to make a difficult decision.

Sweden is no longer safe for Märtha and the children, but all routes to London are blocked by the Germans. When help comes, it is from the most unexpected source.

In the United States, Märtha and her children are showered with the attention of the president. But when German bombs destroy London, she fears for Olav's life.

Märtha begs the president to help Norway, but he has promised his voters that the United States will not join the war. Their friendship falters.
