A great study of the consequences of indulging in utopian idealism without either practicality or realistic preparedness. Harrison Ford plays a man who has a great dream of living in the wilderness isolated from civilization, but who is dangerously naive about both nature and human nature, and therefore woefully underprepared to deal with the menaces of both. A true classic.
