An FBI deep-woods tracker captures a trained assassin who has made a sport of hunting humans.

Aaron Hallam: What if there was a species above us in the food chain? How do you think you'd feel if that species lost total respect for us... and started slaughtering us wholesale?

Narrator: [voiceover] God said to Abraham, "Kill me a son." Abe says, "Man, you must be puttin' me on." God say, "no"; Abe say, "what?" God say, "You can do what you want, Abe, but the next time you see me comin', you better run." Abe says, "Where do you want this killin' done?" God says, "Out on Highway 61."
L.T.: [talking about Aaron Hallam] He's unusual. He can kill anybody without regret. Most of the poeple he killed never knew he was in the same room as them.
Aaron Hallam: If you cross this line, you better be ready to kill me.
L.T.: [speaks to a group of elite US soldiers] I will teach you how to kill. Quickly. Accurately. Efficiently. It will become a reflex action. You will learn how to enter a combat zone and evaporate into shadow. You will learn how to survive... or you will not!
L.T.: If I'm not back in two days, it'll mean I'm dead.
L.T.: They're coming for you.
Aaron Hallam: They've been coming for me for a long time, L.T.
L.T.: I made him what he is, I can stop him.
Aaron Hallam: When you kill with your own hands there is a reverence. There's no reverence in what you do.
L.T.: [speaks to 'the best of the best' of the US Armed Forces] Once you are able to kill mentally, the physical part will be easy. The difficult part... is learning how to turn it off.
Hewitt: Your actions resulted in the injuries and death of unarmed civilians.
Aaron Hallam: They had weapons.

Narrator: [voiceover] God said to Abraham, "Kill me a son."
Hewitt: He's a killing machine. There is no way he can be indicted or tried in open court, or any court. He cannot be processed, interviewed, charged with a crime, or copped out as a psycho. His picture cannot appear in any newspaper. As far as the world is concerned, sir, Aaron Hallum doesn't exist.
