This documentary follows ex-spy Alexander Litvinenko from his forced exile from Russia, to his death from poisoning in November of 2006.
The spy game is a serious business, and throughout history, the tools and technologies developed for it have mattered as much as the spies themselves.
How Vladimir Putin has used his experience as a spy to create and lead modern Russia: arrogance, anger and betrayal; military interventions, cyber-attacks and political assassinations.
