The experience begins as the gates are opened and the participants encounter Eden for the first time. Through woodland, they must find each other, battle the elements and begin to build a new home.

The group try to work out how to organise their new world. Having moved into Eden, the 23 must now learn to live with each other, a task that's harder for some than it is for others.

With rations still scarce, some of the group are battling weight loss and fatigue. Army officer Jack leads a splinter group to build their own winter cabins, causing a major row.

Spring arrives in Eden, lambs are being born and one of the male members of the camp sets his sights on one of the girls. Someone also tries to split the camp by creating an 'A Team'.
