Sixteen strangers embark on a 14-day trek through the perilous New Zealand Alps to reach a distant peak. Each holds part of a $1 million prize, but only those who survive the harsh terrain, Antarctic winds, and intense challenges will win. They face eliminations and twists from the "Mountain's Keeper," testing their morale and unity. Their greatest challenge is to stay together and reach the summit on time—failure means losing the entire prize.
