Berlin Station follows Daniel Meyer(Richard Armitage), a newly anointed case officer who has arrived at the CIA foreign station in Berlin to uncover the source of a leak who has supplied information to a whistleblower. Guided by jaded veteran, Case Officer Hector DeJean (Rhys Ifans) — a darkly charming, tenacious agent who works for Chief Steven Frost (Richard Jenkins) — Daniel learns to contend with the rough-and-tumble world of the field agent — agent-running, deception, the dangers and moral compromises.
Tomita plays Sandra Abe, a quiet presence lording over the efficient operation of Berlin Station while having an affair with her boss, Steven Frost. Orser is Robert Kirsch, a devoted and successful Deputy Chief who digs intelligence out of the capital through a mix of force, diligence and cleverness. Dillane will play Deputy Liaison Gerald Ellman, a gentle, reserved man who plans his transfer to Budapest, but finds himself in a position of being collateral damage; and Schütz is Hans Richter, an old-world spy who has risen, against all odds, to the highest ranks of the BfV.
