How do you protect the truth, in a world where lies are daily currency? And with the proliferation of deepfakes, how can we trust what we see?

It's been 12 months since Rachel Carey broadcast a live deepfake of a government minister to the nation, exposing the UK intelligence service's clandestine video manipulation programme known as Correction.

Amidst an inquiry into the unlawful use of Correction, Carey has become Acting Commander of Counter Terrorism Command, determined to regain the public's trust in surveillance technology through the new Operation Veritas camera system.

And then it happens: a brutal and exceptionally well-coordinated act of terror aimed right at the heart of the British establishment that leaves behind just one witness.

The more Carey investigates, the deeper she is drawn into an unfolding geopolitical crisis that infects the British political establishment, the security services, and the media. The conspiracy reaches deep into the State, but just who is pulling the strings?

Caught in an increasingly violent situation, and with few allies left to trust, what sacrifices will Carey be willing to make?

本剧引入了“客串主角”的概念，即每季一个女主以外的新主角。第一季的Callum Turner不会回归。 新季将再次质疑眼见是否一定为实。英国正遭受围攻：被黑客攻击的新闻动态推送、被操纵的媒体，以及政治中出现的干涉。在英国「校正」部门站稳脚跟的Rachel Carey高级督察，发现自己正处于一场新的阴谋之中，面临着一个新的目标。

可是，当她甚至不能信任自己最亲近的同事时，又要如何解决这起案件呢？ 相较第一季的监控问题，情况更加恶化。故事将讲述“隐形”杀手、深度伪造科技的可怕崛起、政府与大型科技公司之间日益紧张的关系，和英国媒体内部核心的腐败。 Holliday Grainger回归饰演女主角Rachel Carey高级督察。

Paapa Essiedu（《我可以毁掉你》）饰演新客串男主Isaac Turner议员，一位年轻的后起之秀政客，有志于最高层职位。

英国士兵肖恩·埃默里（卡勒姆·特纳 饰）被控于阿富汗战地滥杀无辜，人权律师团队指出控方视频证据缺陷，使其重获自由与幼女团聚。然而伦敦街头一段夜间视频监控却又再次颠覆他的生活，迫使其不得不重新为自由而战。新晋督察瑞秋·凯瑞警探（荷丽黛·格兰杰 饰）在主持调查的过程中逐渐发现，真相有时可能只是角度问题——那么她这一次是否该相信肖恩·埃默里？

 在眼下这个“后真相时代”，面对漫天蔽野的假新闻和瞒天过海的情报机构，我们是否还能相信自己的眼睛？ 剧集由2013年英国电视学院奖（BAFTA TV Award）纪实类最佳导演本·切南（Ben Chanan）创作编导并执行制作，并由盛日电视（Heyday Television）为英国广播公司第一台（BBC1）制作。
