It begins with murder. In Sao Paulo, Brazil, an assassin shoots a powerful businessman. The assassin is then later murdered, setting into motion an international manhunt drenched in blood. Chief Investigator of Interpol Peter Reeger becomes involved, and the case quickly turns personal. The killer taunts Peter, adding to the extreme weight of emotional baggage he already carries. Now tangled in the hunt for this madman are mercenaries, hired hit men, and crime syndicates. Within the chaos, two specific men remain drawn together-one a tortured Interpol hero and the other a psychotic, cannibalistic murderer. Close to drowning in terror, Peter must claw his way out of his own nightmare to end the ritual killings of a man who strives to pull Peter into the abyss.
