The highest and most bitterly cold peak in North America is also the most deadly, and as the season turns, the brave rescuers who usher the frightened and endangered climbers to safety prepare for another year of saving lives and deciphering the mystery of the great mountain known to many as Denali. With over 1,000 climbers attempting to summit this spectacular peak every year, the doctors, mountaineers, rescuers, and military men who patrol the area are always prepared for the call to come in reporting a tragedy. This year is different though, because this is the year that the team charged with rescuing wayward climbers will put their lives on the line in to partake in a bold experiment staged to find out just how the elements can overwhelm those the healthiest and most experienced climbers.
