After surviving last year's record breaking cold, the Mountain Men return more prepared than ever to do battle against Mother Nature, but unpredictable extremes in an ever-changing world force them to find new ways to adapt or die.
Morgan gets caught in the grips of an ice desert with no shelter in sight and Marty's return to Alaska's Revelation Mountains takes an unexpected turn.
Morgan's survival hangs on a critical airdrop; gale-force winds threaten to destroy Marty's cabin; Tom finally gets a breakthrough that could end his losing streak.
In Alaska, Marty Meierotto completes his cabin build just in time for his family to touch down in the Revelation Mountains. While in Montana, Rich Lewis has a real-life cliffhanger as his dogs go one step too far in the pursuit of a bobcat.
It's a race against the end of winter as the melt sets in. Marty gambles on thin ice, a predator awakens in the Yaak and Rich launches a rescue mission.
