Watch on the Rhine

Anti-Fascist German engineer Kurt Muller, with his American-born wife, Sara, and their three children, returns to the United States in 1940 after spending 17 years in Europe, where Kurt has engaged in underground resistance to the rising Nazi threat. Unscrupulous Romanian count Teck de Brancovis, a houseguest of Sara’s family in Washington, D.C., discovers Kurt’s secret and threatens to expose his activities to his contacts at the German embassy.
