March, 1933. The weak German economy is in peril. Winston Churchill wants to push it over the cliff with a boycott of German exports and take with it the new Nazi government whose brown-shirted SA thugs are terrorizing Germany's Jews.
Working with Rabbi Abba Hillel Silver, Churchill enlists the help of his goddaughter, Hearst photojournalist Mattie McGary, and her fiance, the lawyer and ex-Army intelligence agent Bourke Cockran. Mattie's task is to find out how the Nazis plan to defeat the boycott. Cockran's assignment is to recover microfilm containing sensitive commercial information on German exporters compiled by German patriots opposed to the Nazis. With it, the exporters' competitors will be able to steal Germany's foreign customers with comparable goods at lower prices.
The Nazis are determined to fight back. To oppose the boycott, they find two unlikely allies. One is the Jewish Authority in Palestine who is negotiating with the Nazis to sell out the boycott in exchange for the Nazis allowing German Jews to emigrate to Palestine with funds in excess of German currency controls. The negotiations are top secret and when Mattie gets too close to the truth, both the Nazis and their Jewish allies in Palestine are determined to stop her at any cost.
The second Nazi ally is FDR and the U.S. government who also oppose the boycott because of the damage it will do to American investors. When American agents learn of Cockran's quest for the microfilm, they team up with Hitler's black-clad SS and Jewish agents from Palestine to stop him and get the microfilm.
The deadly battle between Churchill's agents, Mattie and Cockran, takes them from New York to London, Paris, Berlin, Budapest, Prague, Copenhagen, and Stockholm pursued by the strange bedfellows of Nazi, Jewish and American agents working together. Finally, at Mattie and Cockran's wedding in Scotland, their enemies kidnap Cockran's son and Churchill's daughter and offer to trade their lives for the microfilm.
