Berlin, 2011. A former Stasi double agent, Ludwig Licht, who after the fall of the Berlin Wall works as a freelance problem solver and is the number one customer in the bar he owns in Kreuzberg, Berlin, is asked by his old CIA contact to come out of retirement and work one more case. The case involves the whistle-blowing organization Hydraleaks, whose leader, Lucien Gell, is currently off the grid. One of their members is on the run after three of her associates are assassinated in Morocco. Licht's old partner, Clive Barner, is now head of CIA's Berlin office and realizes the case may have major implications. Licht, who has borrowed money from gangster Pavel to uphold his bar, sees this as an opportunity to make some cash to get rid of his debt.
