At base camp, the couples must construct shelters to save themselves from hypothermia — and compete for a night with the Oses at their mountain home.

Split up by gender, the couples test their critical orienteering skills. As the winners fly to Ose Mountain, the rest get schooled in firearms.

After working together to create a sled dog trail, another couple choppers to Ose Mountain while the rest learn how to kill and field-dress a bison.

A night in bear country with minimal supplies and gear determines the last couple to visit the Oses, who send two other couples packing for home.

The Oses make a tough decision. Then one partner from each of the remaining three couples spends two days at a remote wilderness camp alone.

Only two couples remain to vie for the Ose Mountain claim. Who will spend their first night as the new owners of an idyllic home in Alaska?
