1968. LBJ is running out of time. Having abandoned his own re-election campaign, the President turns to the one achievement that might redeem his final months in office: peace in Vietnam. But as the US election tightens, the CIA begins to pick up signs that Nixon’s campaign may be using secret back channels to keep South Vietnam away from the negotiating table. For LBJ, it could destroy his final hope of peace. For Richard Helms and Eloise Page, it is a dangerous collision of espionage, democracy and power.

Starring Kim Cattrall, Kelsey Grammer, Johnny Flynn and David Duchovny.

America is losing faith in Vietnam. After a major communist offensive shocks the public and exposes the fragility of the war effort, LBJ faces pressure from every side. The generals want more troops. The country wants answers. And inside Washington, the search begins for a strategy that can deliver results without admitting defeat. Into that vacuum steps Bill Colby, played by David Duchovny — the CIA’s Far East chief and one of the Agency’s most important Vietnam specialists. His influence inside the Agency is only beginning. His answer is the Phoenix Program: a plan to identify and dismantle the Viet Cong’s hidden political network across South Vietnam. Colby believes the program can bring order, discipline and better intelligence to a failing war.

But in Vietnam, even precision has a cost. What begins as an attempt to understand the enemy will become one of the most controversial operations in the CIA’s history. For LBJ, Phoenix offers the hope of progress. For Colby, it is the making of a career. For the Agency, it is another step into the shadows of Vietnam.

Starring Kim Cattrall, Kelsey Grammer, Johnny Flynn and David Duchovny.

The war in Vietnam is no longer happening far away. Images of conflict flood American living rooms and the anti-war movement explodes. LBJ is convinced the protests cannot be truly domestic. Someone must be behind them: Moscow, Havana, perhaps both. He orders Richard Helms and the CIA to find the foreign influence driving unrest at home. But as the Agency moves closer to spying on American citizens, Eloise Page begins to see a different force at work. Not a secret network. Not a Soviet plot. Something much more powerful, sitting in plain sight: television.

Rumours are spreading through the Bolivian jungle: Che Guevara is back. For Washington, the possibility is explosive. The world’s most famous revolutionary may be trying to ignite another insurgency in the Americas — and the CIA cannot afford to let his legend grow. But before they can act, they need proof. Is it really Che? Or another fighter hiding behind the myth? As the Agency trains Bolivian forces for a covert hunt through brutal terrain, Eloise Page and Richard Helms face a delicate mission: find the revolutionary, prove his identity, and stop a symbol from becoming a movement.
