Ten new participants brave Alone's most terrifying location yet in pursuit of $500,000. One participant is forced to make a life-or-death decision, and all must contend with Chilko Lake's deadliest predator: the grizzly bear.

More participants begin their fight against the land's harsh conditions and its abundant grizzly population; one survivalist builds a unique shelter, while another tests their might against the treacherous waters of Chilko Lake.

While some participants continue to work on new ideas to gain calories, others hunker down to try and last as long as they can. With the struggle to procure food this late in the competition, the threat of being pulled out becomes all the more real.

The mental toll of isolation begins pushing participants' psychological boundaries to their limits. One survivalist gets caught in an off-putting standoff, while the increasing emotional cost of solitude afflicts another.

With only 3 left in the competition, the participants struggle to claim the $500,000 prize. While some continue to deal with the mental game, a new predator threatens a survivalist's longevity.

As the challenge comes down to the final four participants, Chilko lake continues its onslaught on those struggling to survive.
