This season, the Mountain Men continue to carve their lives from the untamed ranges of America, while facing one of the coldest and meanest winters in decades. Predators are a constant threat for Marty, Tom, Eustace, Rich, Charlie and new mountain man Kyle. They all know that the meanest beast in the wild is Mother Nature herself, and this year she’s fixing to give them hell. They will brave the extremes of remote wilderness where one single misstep can send you into the bone-breaking jaws of a grizzly bear or leave you stranded with no help for miles around. As they struggle to stay one step ahead of the deadly cold, each will take on new challenges to maintain their life in the wild and ensure their survival.
