《致命面紗》是一部國際間諜驚悚片，講述兩個女人之間令人驚訝和令人擔憂的關係。兩人在從伊斯坦堡到巴黎和倫敦的路上玩著一場關於真相與謊言的致命遊戲。一個女人帶著一個秘密，另一個女人的使命則是揭露這個秘密，避免成千上萬人喪生。在暗處，美國中央情報局和法國對外安全總局的任務控制人員必須暫擱分歧，儘管這看起來很困難，並共同努力避免潛在的災難，以免為時已晚。

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.
