Four city-dwelling friends (Jon Voight, Burt Reynolds, Ned Beatty, Ronny Cox) decide to get away from their jobs, wives and kids for a week of canoeing in rural Georgia. When the men arrive, they are not welcomed by the backwoods locals, who stalk the vacationers and savagely attack them in the woods. Reeling from the ambush, the friends attempt to return home but are surrounded by dangerous rapids and pursued by a madman. Soon, their canoe trip turns into a fight for survival.
