Berlin Station

CIA officer Daniel Miller arrives in Berlin on a clandestine mission to unearth an anonymous whistleblower, alias Thomas Shaw, and reunites with his old friend Hector DeJean; as Daniel gets closer to Shaw, his quarry reacts in a murderous fashion.

As Daniel pursues Shaw, Station Chief Steven Frost, Valerie Edwards and Robert Kirsch gather intelligence on a Georgian Islamic radical in order to avoid an extraordinary rendition by Langley.

Frost and Robert worry their secrets will be discovered when Langley investigators sweep Berlin Station; Daniel's Shaw hunt is compromised when Hector bugs his phone; the station's surveillance of Aleksandre Iosava turns up bad behavior by an agent.

Daniel begins a dangerous operation that brings up difficult memories of his first posting in Chechnya and the beginning of his friendship with Hector; Steven Frost finds a way to position himself for promotion at the cost of his deputy.

American and German interests align when the Station learns the subject of Shaw's next leak is Chinese defector Houjin Lin; Daniel teams with Esther Krug to get Lin out of the country before the leak breaks, pre-emptively countering Shaw's attack.

Valerie's investigation into Aleksandre and Ruth Iosava comes to a head in a German/American sting operation involving CIA officer Clare Itani, who is also Hector's lover; Langley's unannounced participation changes things from bad to worse.
