"Europe, at the beginning of the 20th century: the beautiful dancer Mata Hari has collective manhood at her command. The performances of the native Dutch girl as an oriental nude dancer are an overwhelming success in the unbounded luxury and enjoyment of life of the Belle Epoque. Her daring dancing shows attract influential gentlemen from the realms of industry and politics, amongst these the attractive Swiss Oscar Samsonet. He quickly realizes that this exotic beauty can be ideally used to realize his aims. Lured by her taste for adventure and the prospect of making a fast buck, Mata Hari becomes a spy. She uncovers highly sensitive military secrets using her finesse, charm and seductive skills. She thereby gets caught between the fronts: the Entente ran a frantic arms race with the Central Powers, World War I is threatening on the horizon."
