Classic ITV detective drama, starring Richard Bradford as McGill, the ex-CIA agent reduced to working as a gun-for-hire and private investigator. McGill, a discredited ex-CIA agent reduced to working as a private investigator, travels the world as a ‘gun for hire’. His unorthodox approach and his strong sense of personal integrity often bring him into conflict with both his employers and the authorities and make him more enemies than friends... He finds himself tangling with crooked governments, hunting down the man who framed him, and being drawn back into the world of espionage with an assignment in East Germany.
