Intent on seeing the Cahulawassee River before it's turned into one huge lake, outdoor fanatic Lewis Medlock takes his friends on a river-rafting trip they'll never forget into the dangerous American back-country.
Four Atlanta friends - Lewis (Burt Reynolds), Ed (John Voight), Bobby (Ned Beatty), and Drew (Ronny Cox) – decide to canoe down the Cahulawassee River out in the Georgia wilderness. They see it as a test of manliness whilst also wanting to experience this part of nature before the whole valley is flooded over to make way for the upcoming construction of a dam and lake. But the perils of nature are not the only dangerous things in their midst, unfriendly wood folk are about to bring another dimension in terror.
