A rogue special-forces soldier is tracked down by his former mentor in this action thriller from director William Friedkin (The French Connection, The Exorcist). In his first role since winning a Best Supporting Actor Oscar in 2001, Benicio del Toro stars as Aaron Hallam, one of the U.S. military's most skilled hand-to-hand combat operatives. In the years following his successful assassination of a Serbian warlord in late-'90s Kosovo, Hallam finds himself plagued by traumatic flashbacks of death and destruction, so much so that when he finally returns home, he regresses into a feral, survivalist state in the woods of the Pacific Northwest. There, he deliberately and elaborately hunts and kills poachers who happen to cross his path. When the FBI investigates the murders, they call in the man who taught Hallam everything he knows: retiree L.T. Bonham (Tommy Lee Jones). As the instructor pursues his unhinged former pupil, Bonham begins to learn about key events in Hallam's life that pushed him over the edge.
