Deliverance

In the unfamiliar Appalachian backwoods, a weekend of male bonding for four inexperienced campers turns into a gut-wrenching fight for survival against the merciless forces of nature and the brutality of man. Their only escape is a terrifying canoe ride down the raging rapids of the Chattooga River. If their heartless pursuers don't kill them, the treacherous waters just might.
