Gail is a professional at white water rafting. She twigs every day, and is in very good shape. She takes her family on a rafting trip down the river where she was a guide, but has no idea that the planned trip is about to become a nightmare. Two escaping robbers with a handgun meet and join them. Only later does Gail realize that they are dangerous criminals, but it's too late. They force them to stay together, and keep cruising down the river. Their lives are risked not only by the men, but also by the river which becomes more stormy and wilder.—rsilberman
