Survival (2006)

There are terrible people in the woods, not quite crazed redneck, not quite insane cannibalistic maniac, not quite a chainsaw wielding skin wearing gram pa's boy. This time it's a pair of psychotic siblings, who love to capture and torture their prey. Using physical and psychological torture methods, they bring their victims to the very edge of sanity, then release them back into the wooded area that surrounds their home with only two instincts intact: killing and survival.
