《致命面纱》是一部国际间谍惊悚片，讲述两个女人之间令人惊讶和令人担忧的关系。两人在从伊斯坦布尔到巴黎和伦敦的路上玩着一场关于真相与谎言的致命游戏。一个女人带着一个秘密，另一个女人的使命则是揭露这个秘密，避免成千上万人丧生。在暗处，美国中央情报局和法国对外安全总局的任务控制人员必须暂搁分歧（尽管这看起来很困难），并共同努力避免潜在的灾难，以免为时已晚。

An ex-terrorist, Madina Taburova, who was presumed dead, turns up in Helsinki seeking political asylum. Using a fake identity, the Intelligence Agency officer Mari Saari has to befriend this ex-terrorist to find out why she’s here. In order to uncover the mystery, Mari Saari has to form an unlikely partnership with an older streetwise narcotics cop. But everything is not as it seems.
