Beginning with chillingly prescient footage of ex-Russian security agent Alexander Litvinenko predicting his own murder, this investigation into his death offers fascinating insights into a real-life James Bond mystery that gripped the world.
It also makes clear that Litvinenko had been under threat from a murky underworld for many years, as director Nekrasov uses footage dating back to 1998 to unpick the unsolved murder and expose a complex political situation.
Featuring interviews with several contributors who are now dead, including gunned down journalist Anna Politkovskaya, this is a brave, terrifying piece of work.
