A movie where a boy kills his crazy mother who, later (several years?) , go to a cabin with 3 male friends. While out in the woods, the men discover a strange area which, for whatever reason, allows them to hear everything within the zone no matter how far away they were. Spending time in this zone slowly makes them go insane and they begin to do crazy things like scalp one friend and fire a nail gun at the other and they’re all totally cool with it. One character looks like Bradley Cooper.
