The participants test new strategies to get hold of food as the predators pose a serious threat; someone is concerned they consumed a poisonous plant.

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.

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.

As they reach a month in the wild, winter weather raises the stakes for each participant. An unwavering grizzly causes one competitor to prepare for battle, and another's desperate attempt for food suddenly turns life-threatening.

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.

The remaining participants fight to protect their food supplies as they face continued pressure. One survivalist's shelter poses a serious threat, while another's health takes a consequential hit.
