After a visit from a Stalinist-era bodyguard who claims to have stolen a personal notebook belonging to Joseph Stalin, radical historian Fluke Kelso (Daniel Craig) digs deeper to prove its existence. But in the process, Kelso stumbles upon evidence that points to a secret Stalin legacy that may alter Soviet history. Yekaterina Rednikova and Gabriel Macht also star in this British made-for-TV thriller adapted from Robert Harris' novel.
