As their teammates attempt to set up camp, the hikers find that Vancouver Island's terrain is even more punishing when on the move; the island beats one pair into submission, while another grapples with a devastating accident.

Desperation sinks in as the hikers struggle to make the final push to their teammates; exhaustion leads one participant straight into the path of a predator, and into a dangerous confrontation.

As freezing temperatures punish Vancouver Island, the remaining pairs all face game-changing scenarios; one participant is hit with a crippling illness, while another's temper drives a wedge between him and his teammate.

Family members are dropped off miles apart and must navigate the unforgiving terrain of Northern Vancouver Island to find each other; to win the $500,000 prize, the competitors must build their own shelters and forage for their own food.

As time presses on and temperatures drop, the final teams grapple with a strong desire to tap out; however, the $500,000 prize is hard to give up on, and the participants push themselves until one reaches the breaking point.

As Vancouver Island is pummeled by torrential rains, the remaining teams scramble to avoid freezing flood waters; one team attempts a massive construction project, while another must choose between betraying a family member and tapping out.
