After the second episode only 12 people remain. Trust is a matter of life or death, you have to trust your team in order to survive. The first challenge causes problems with relationships as tensions grow fierce. The recruits single out the members who they think are the least trust worthy and this creates more problems for the recruits. The next challenge is a forward abseil off the top of a waterfall where the jumper's life is in the hands of the person below holding the rope.
