The contaminated fruit of a single tree sets off a shocking chain of events within a 24-hour period; illness and panic spread through the group, bringing into question whether anyone will make it to Day 40.

Ryan separates from the group and finds his camp circled by a deadly animal while he is sick and helpless.

Starting with no tools, the survivalists scramble to prep for a brutal storm and two competitors are at risk immediately; a cutthroat survivalist puts the others on notice.

Competitors battle for new resources in a grueling migration across punishing, elevated terrain; an injury puts Matt's challenge at risk; Waz unleashes a game-changing response to Jeff's cutthroat strategy; two survivalists exit the challenge.

As deadly predators begin to close in on the remaining survivalists, they must find the energy to secure food and start their long journey to extraction.

Shocking sabotage and a midnight medical emergency upend the competition; the elimination challenge requires a photo finish; in a test of skills, survivalists must build primitive ladders, torches and hooks to claim critical caches.
