In the second season premiere of this series we meet a new group of climbers ready to tackle one of the biggest challenges on the planet: climbing Mt Everest. They risk their lives to achieve their dream, and on the way to the top they must overcome fear, freezing cold, exhaustion, and themselves.

The team makes its first ascent to a high camp with a strict time limit set by Brice, and Betsy must prove herself in one last climb or she may not be allowed the ascent.

The climb to Camp Two is brutal in both the weather and the outcome as Brice makes his decision on who is grounded.

Finally acclimatized and ready for the final haul to the top, the expedition leaves Base Camp. David Tait and Phurba Tashi are within hours of the summit, but even if they make it, they still have a long way to go to reach their goals.

Tim is lagging behind again, and Russell threatens to kick him off the team. Team One sets off for the summit.

Team One reaches Camp 4 in the Death Zone, and as their bodies begin to shut down from lack of oxygen, there is a grim reminder of the consequences of poor decisions.

Team One is in the Death Zone preparing to set off for their summit attempt, but an injury may sideline one of the team members risking not only his or her summit hopes, but the injured part.

Team Two makes their summit run, but it's the descent that endangers one team member with an 8,000 foot drop to his death.

At three miles above sea level, the base of Mount Everest is already higher than any mountain in the Rockies. The expedition team makes seven overnight stops to get to Base Camp (BC) on the mountain's northern face and will take a full month to acclimatize their bodies before they attempt the summit. The air is thin and the climbers feel physically weak, but the camaraderie is strong. As the team moves to Advanced Base Camp (ABC) at 21,000 feet to begin acclimatization climbs, they are shocked to discover how badly their minds and bodies cope. The expedition members begin climbs up to a ridge at 23,000 feet called the North Col, scaling 1,000-foot ice cliffs along the way.

At ABC, more than 600 climbers prepare for summit attempts. All the climbers on Russell Brice's expedition must prove they're strong enough to climb from ABC to the North Col in less than five hours or he will not allow them to continue. Russell spots a period of light winds in two weeks' time that looks ideal for an early summit attempt. To make this window, however, he'll have to push both his Sherpas and climbers extra hard to be ready two weeks early.

With all high camps ready and a promising forecast, Russell splits the group into two teams for the five-day, 8,000-foot summit climb from ABC. The strongest climbers are assigned to Team One guided by Bill Crouse, including L.A. firefighter Brett Merrell, ER doctor Terry O'Connor and asthmatic climber Mogens Jensen. Led by guide Mark Woodward, Team Two includes double amputee Mark Inglis, Hollywood biker Tim Medvetz and Lebanese climber Max Chaya.

Team One is the first to head into the death zone, where the extreme altitude shuts down digestion and the body starts to consume its own muscle tissue for energy. After only a few hours at the top camp, Team One leaves in the darkness at 1 a.m. for the summit. Almost immediately, they are caught in a frustrating human traffic jam that stops them in their tracks. If they can't pass some of the slow climbers on the ropes ahead of them, they could run out of time…and oxygen.

Members of Team One cope with the aftermath of their summit attempts. Many climbers are in danger from frostbite in the minus 40 degree F temperatures. Russell instructs Team Two, now at the top camp and ready to begin their summit attempt, to leave two hours early to try to beat the traffic. Although this might help, it also means an extra two hours in the elements before the sun rises on a very cold day. While some climbers make a strong start, others immediately struggle.

As everyone descends, the entire team suffers from the extreme cold. Frostbite affects more climbers on Russell's expedition than ever before. For each one who made the trek, whether or not they made the summit, the most important trip will be the one home. The climbers reflect on this year's expedition and whether or not they'll return to the mountain.
