This tv show follows Daniel Meyer, a newly anointed case officer who has arrived at the CIA foreign station in Berlin, Germany. He is charged 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 jaded 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?
