Chris Morehouse is a contract agent for the CIA.
This is not unusual since the Agency makes use of a lot of contract workers to provide great deniability. Morehouse is a bit different in that he is a British citizen. But as he shows when we first meet him, the man has terrific instincts, impressive powers of observations, and very, very nice reflexes. This not only helps him stay alive in nasty situations, it helps immensely keeping those he is protecting alive and helps him pull off some quite difficult missions.
