After a spate of grisly murders performed in an almost ritualistic way, the experienced survival expert and former military instructor, L.T. Bonham, is summoned to track down the elusive and shockingly familiar killer: one of his best pupils, Aaron Hallam. Holed up in the wet and tangled wilderness of Oregon's Silver Falls State Park, Aaron--now a tormented and delusional killing machine--will soon come face-to-face with his grizzled mentor, in a no-holds-barred hand-to-hand combat. Suddenly, age; experience; strength, and the feral will to survive, blur the line between a hunter and his prey. Now, who is the hunted?
