One of the great romantic classics of the Thirties. Radiant Vivien Leigh plays an Allied double agent in 1915 Stockholm. The Germans, who suspect she is passing secrets to the French, send Chief of Intelligence Conrad Veidt to catch her only to have the two fall hopelessly in love. Their feet set on opposite paths of doom, they are led inexorably towards the moment when each must choose - between love for each other and love of country.
