John orders Snake tribe to move to Hunt camp, but the Cray tribe has already been and cleared all the useful tools and taken all the fruits and nuts off the trees. Tempers flare as hunger and hardship take their toll, health detoriates and a divide emerges in one tribe.

With rations running low and the animal traps empty, Steve organises a fishing party. After trekking for more than three hours the hungry anglers cast their lines, but while they get many bites landing a fish proves to be difficult. Back at camp, hunger claims its first victim as Kym has to have medical help.

The first 12 volunteers arrive at their camp and appoint a leader. The scouting party finds an abandoned camp by a lake and persuade the others to move - unaware that a second tribe will be arriving in 24 hours' time and that this is their allotted camp.

A joint tribal hunting party sets up base at Wood camp. After outstaying their welcome in the Cray camp, Snake leader John moves his remaining tribe to their new home.

The tribe arrive in their new home - a remote forested wilderness.

The second tribe arrives and finds that the first tribe have settled in their allotted camp.

In the final days of the experiment, only five of the original 20 tribe members remain. With the recent shock departure of Paul and Mike still seriously ill, Mel finds the strain of carrying the weaker members is pushing her to breaking point.

The tribes build a monument as a legacy of their experience.

Day 8 sees the tribe with only enough rations for another day. When another fishing trip yields little in the way of nourishment, the condition of the tribe forces the survival experts and the producers to decide whether to intervene or halt the experiment.

The Crays get an unwelcome surprise when the Snake tribe moves in with them while their new camp is being built.

New leader Mel is determined to conserve rations and supplement them with foraged roots, berries and fish, but Paul is determined to go hunting. JP threatens to leave when a meeting is called to discuss his laziness.

Steve tries to get the team not to make the same mistakes that they made when they allowed the deer meat to be wasted. Paul attempt to create a boar trap whilst an unpleasant discovery is made by Kim.
