Transitioning from his job as a CIA analyst in the U.S., cerebral officer Daniel Miller’s new mission puts him under cover at the agency’s Berlin branch, tasked with sorting out messy cases involving damaging leaks, whistle-blowers, terrorism and more. Mentored by jaded veteran officer Hector DeJean, Daniel learns the disorderly world of field work means dealing with deception, danger and moral compromises. As he dives deeper into the German capital’s hall of mirrors and discovers conspiracies that lead back to Washington, D.C., he wonders if anyone can ever be the same after a posting to Berlin.
