Winston Churchill is travelling through Morocco on his way to Casablanca during World War II. Lurking in every corner are spies and agents working for the Nazis - who have a daring plan to kidnap Churchill and take him prisoner. It's the job of three expert counter-espionage agents, Cooper (Jason Connery), Franchetti (Francisco Quinn), and Lorna (Jinny Steffan), to make sure that Churchill arrives at his destination intact. The General (Glenn Ford) decides that Churchill will take the Casablanca Express, a train known for its security record. Churchill is secretly brought on the train with a squadron of soldiers to protect him. The train leaves as planned and seemingly the Allies' plan has gone without a hitch. But when the Nazis seize the train and take Churchill hostage, it's up to one man - Agent Cooper - to stop the Nazis from taking Churchill back with them to Berlin.
