With only six days to go, the tribe still doesn't have enough food to see them to the end. After Paul's shock departure and with Mike seriously ill, just four remain in camp. Mike is so malnourished, the medic is concerned he could have liver damage. Mel is working harder than ever and is worried she'll be the next one to crack.

It's mid-November and the tribe are worried whether Mel's plan to ration the food for the remaining two and a half weeks will work. Paul Barnes isn't convinced: he's been busy setting deer traps. Although unsuccessful, he and Mike are exhausted from hours of hunting. Paul becomes more and more desperate in his pursuit of wild game and more and more exhausted. With Paul on the verge of collapse, an unlikely hero steps up - JP. With no hunting experience, can he tap into his primal instincts and bring back a boar?

Winter is approaching and the tribe needs to ensure they have enough food and wood to survive the next four weeks. Since Steve left, Mel is in charge of rations. Paul has had bronchial pneumonia for three days, but when he returns to the camp he challenges Mel on her plan. With so much work to do, the tribe can't afford to lose another member.
