Plot: The possibilities of getting lost in the Grand Canyon escalate dramatically if you choose not to properly plan your trip into the canyon, use uncertified guides (esp with drinking problems), no wilderness survival training, no maps or compass, and have no way of communicating with the outside world. Having no food or water, lost in the canyon, under high heat conditions can alone kill you, much less the idea of wild animals attacking you? I must point out that idea about wolves in the Grand Canyon Park and outlying areas attacking people is totally absurd! Whoever thought this one up did not do much research because wolves, though they have been spotted in these areas on occasion, are for the most part rare and shy of humans. Timber wolves, which the movie portrays, mainly exist in Canada and the northwestern states towards Canada. So this part is completely unrealistic for an already busy plot. Wolves only act like this when they are starving to death, but the Timber wolves shown in this movie looked pretty well fed.
However this movie does make you think twice about roughing it alone out in no man's land. If you don't have the stomach to see what people have to do under desperate circumstances, then perhaps you need to look for another movie?
