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'.

Life in Eden proved too tough for some, and after just three months, two had already left. By the summer, hunger pervades and divisions within the camp are already becoming apparent.

As three more people leave the camp, the men significantly outnumber the women. Tensions grow between the sexes. Meanwhile, Oli and Rachel develop an intense friendship.

Oli confronts Anton and Ralph about their isolated house in the woods. Their showdown boils over in a dramatic conclusion that changes the group forever.

The atmosphere in Eden remains hostile with the community effectively split in two. The `Valley Boys' are increasingly antagonistic. Rob finds it intolerable and Katie is furious.

On Christmas Day the community join together to celebrate. Contraband is getting into the camp. But what greets the group on the morning of their final day in Eden is catastrophic.
