The action takes place in the early 1960s. The story revolves around a British spy named Scott Fielding, who travels to the capital of Germany with a crucial mission - to find a spy among the British diplomats, and perhaps even among their allies. Berlin is filled with a tense atmosphere, as every other person in this city is a spy or a double agent. One wrong move could lead to a nuclear threat. The military forces of the world powers are divided by a very fragile line.
