Cross multiple waterways, through miles of deep muskeg and climb hundreds of feet of mountain in search of caribou.

The guys push down river but have barely enough energy to set camp.

Another day at Prayer Point presents Casey with another opportunity.

The guys have more questions than answers and find an abandoned trappers cabin.
