Daniel Miller has just arrived at the CIA foreign station in Berlin, Germany with a clandestine mission: to uncover the source of a leak who has supplied information to a now-famous whistleblower named Thomas Shaw. Guided by veteran Hector DeJean, Daniel learns to contend with the rough-and-tumble world of the field agent: agent-running, deception, the dangers and moral compromises. As he dives deeper into the German capital's hall of mirrors and uncovers the threads of a conspiracy that leads back to Washington, Daniel wonders: Can anyone ever be the same after a posting to Berlin?

Season 2 opens in the thick of a New World Order that has taken root and is steadily deepening. In the wake of the Far Right tide sweeping across continental Europe, Germany finds itself on the precipice of a pivotal election. Alt-Right party leader Katerina Gerhardt has capitalized on the refugee crisis and economic strife to woo disillusioned voters fed up with the status quo, seemingly poised for a big win. Our heroes at Berlin Station must determine the nature of the threat she poses, and what role they should play. Is Katerina is a viable candidate with a controversial message who should be protected by the democratic process? Or, as preliminary evidence suggests, is she colluding with terrorists?

In season 3, newly promoted to Chief of Station, Valerie Edwards sends Daniel Miller and Robert Kirsch on a diplomatic mission to Estonia, where they uncover signs of an impending Russian invasion, threatening to destabilize the NATO Alliance. Daniel stays behind to search for the truth, but goes MIA during his mission. The rest of the team, joined by Special Activities Case Officer Rafael Torres, must work to unravel the conspiracy and bring Daniel home.
