Chase warns them of possible tensions arising as they cross Native American territory, and leaves them to complete the journey on their own. Spirits are lifted when they arrive at their new settlement. But the celebration ends when an encounter with neighboring tribes gives Diane such a scare that she and Mike decide to go home.

The remaining couples find themselves at the mercy of Mother Nature when a giant storm rolls in.
