Seven family member pairs are dropped miles apart on Northern Vancouver Island and must find each other. To win the $500,000 prize, they must survive the island's unforgiving terrain and deadly predators.

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

On Vancouver Island, a seriously injured participant weighs the risks of seeking medical help and sacrificing his shot at $500,000.

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.

Now that most teams are reunited, they dive into the difficult task of surviving together and feeding two people. The final hiker faces a brutal mountain climb that could dash his hopes of making it to camp.

As Vancouver Island is pummeled by torrential rains, the remaining teams scramble to avoid freezing flood waters. One team attempts a massive construction project that could be their key to survival.

The three remaining teams scramble for a long term advantage. One pair runs themselves ragged with an elaborate shelter build, while another hazards the freezing Pacific waters on their own small craft.

After nearly a month on Vancouver Island, the three remaining teams face existential threats at every turn. One participant is forced to fight a raging fire. Rising tensions threaten to end another partnership.

As freezing temperatures punish Vancouver Island, the remaining pairs all face game-changing scenarios. One participant is hit with a crippling illness.
