Agent Tom Quinn returns to the US, his mind a battleground of doubt and shadows. Haunted by visions of the men he'd dispatched over his storied CIA career, he questions his ability to continue in the field. Just as he contemplates walking away, he's offered one last mission-one that could either be his redemption or the plunge into an abyss of darkness, both within himself and within the intricate workings of a potentially disastrous operation. It was to be his Final Pursuit.
