Marcus was an agent in the operative special forces until he confused the location he had to reach to defuse a bomb. The explosion resulting from this mistake led to hundreds of deaths, including the family of his partner, Eli. As expected, Eli still bears them and imputes all the blame for that unfortunate event. Agent Marcus returns to a demon who offers him a job as a soul hunter. Marcus collects souls for the deep world, recovering them and pointing them to his servant, Raquel. But the past is back to him, just when the beautiful Kristen enters his life, and he gets caught up in a battle between Heaven and Hell. Will Marcus be able to save mankind and eventually even redeem his soul?
