俄羅斯，世界上幅員最廣闊的國家。許多人可能對這國家都存有誤解，但有更多有人對她充滿恐懼。在過去的一個世紀，俄羅斯的歷史與國安部門的歷史息息相關。蘇聯政權把國安部門用作打壓和清除異見分子的工具，數百萬人遭其迫害，飽受痛苦。大規模處決、秘密戰爭、鼓吹政變、竊取美國原子彈資料的間諜、黑客攻擊和落毒醜聞等等事件都令這情報機關變成世界上最非比尋常又危險的國家安全網絡。縱然今天的俄羅斯已經發生了許多變化，但國家安全網絡的規模，可以說比以往有過之而無不及，背後的原因跟一個默默無聞的中校崛起有關，隨後他更成為這個大國的總統，他就是弗拉基米爾‧普京。 本紀錄片系列由曾榮獲四個艾美獎的紀錄片導演占美•多倫執導，並訪問了前秘密警察及受害者，訴說昔日的種種。

Russia is the largest country on earth. Misunderstood by many and feared by even more. For the past century, Russian history has also been the history of its security services. They were used by the Soviet state to crush dissent. Millions suffered at their hands. Mass executions, secret wars, coup d’états, spies capable of stealing the atomic bomb from America, hacking and poisoning scandals all add up to the most extraordinary and dangerous security network the world has ever known. But while many things have changed in today’s Russia, that security network is arguably stronger than ever. And the reason behind this is the rise of a lowly lieutenant colonel to President of this vast country, Vladimir Putin.

Directed and produced by 4 x Emmy Award-winner, Jamie Doran, this is the story of the KGB told by its veterans AND its victims.
