New world, new rules. The same old deadly enemies.



CIA agent Sam Hudson has been hunting deadly Russian operative Konstantin for years. Sam tracks Konstantin down to Geneva, Switzerland – but following an ambush, barely makes it back to the US alive.



The Washington higher-ups want Sam to drop his obsession with Konstantin, but he can't let a man who's killed so many slip away again.



When a mysterious caller taunts him right before an attack in DC, Sam realises Konstantin has followed him to American soil. Sam must bring Konstantin down – before Konstantin brings down the nation's capital.



But as he tries to neutralise his old enemy, Sam finds obstacles at every turn, and he begins to wonder if there is someone in US intelligence on Konstantin's side...
