Summary
Four Atlanta businessmen take a canoe trip down a remote Georgia river that is about to be dammed, seeking a weekend of wilderness adventure before the valley is flooded. What begins as a male-bonding escape turns into a harrowing fight for survival after a brutal encounter with local mountain men forces the group to confront violence, moral compromise, and the unforgiving wilderness.
