The Devil's Hole. Four men who went through college together go on hunting and fishing trip to the wilds of Wyoming. They are taken to a mountain lake ten thousand feet in the mountains called the Devil's Hole by the local residents. A helicopter takes them up and will return to bring them down. The men experience wild animalsgrizzlies, cougars, and wolves; one is killed by a wild animal. One man finds out another in the party was having an affair with his wife, which create animosity between the two. The helicopter returns, but the pilot is mauled and killed by a grizzly bear, so the men must trek down the mountain and hike ninety miles to civilization. They encounter wild animals, thick forests, raging waters, starvation, and dehydration. Not all of them make it.
