Plot
John Marlowe is an American surgeon visiting England when he is invited to Vosnia (a fictitious East-European country) to receive the "Kepler Gold Medal" for his contributions to medical science, and, coincidentally, to demonstrate his new techniques on a patient. Midway through the operation, he discovers that he is operating on the Vosnian dictator, General Niva. Niva dies during the recovery period. From talking beforehand with Colonel Galcon, the Minister of Health, Minister of Public Services and Minister for State Security, Marlowe is certain he is doomed—he knows too much—so he makes his escape while Galcon is distracted by Niva's death. With elections coming soon, the general is replaced by a double, and Marlowe is hunted by the state police.
Marlowe's attempts to telephone and reach the American embassy nearly get him captured. While hiding in a theater during a show, he notices a woman singing in English. He goes backstage and enlists the help of the reluctant, half-English Lisa. Marlowe has an idea: inside the coat he was accidentally given in a barber shop, by the barber, they find a wallet containing the ID of a Karl Theodor, and foreign currency, the possession of which is a capital offense in Vosnia. They blackmail the smuggler Theodor into helping them. They are pursued across the country and are on the point of escaping across the border when one of Karl's men, who is leading them across the mountains, is shot by a border guard and killed, and Lisa is wounded. Marlowe refuses to abandon her, and is captured by Galcon's men.
Galcon arranges a "shooting accident" for Marlowe, but as he is about to walk outside to his fate, the substitute for dictator Niva makes a live speech on the radio, and shots are heard. Galcon confirms by telephone that the stand-in has been assassinated. As the people have witnessed the death of Niva, albeit the fake Niva, it is no longer necessary to maintain the cover-up, nor to eliminate Marlowe and Robinson, who are subsequently released and fly to freedom in the West, and ultimately to their new life together in America.
