Using a telescopic lens on a salvaged camera, Douglas thinks he has found a nearby, inhabited island. His plan to build a raft shocks Brett, who cannot believe he wants to leave the paradise they have created. Meanwhile, Susan, having been spurned by Douglas, is manipulated by a vengeful Brett and a witch-hunt begins. Douglas now stands accused of sexual assault, conveniently scuppering any raft-building plans by having to stand trial. Arnab is recruited by Brett to help seal Douglas' fate, but is undeterred in his own plan to build a glider and finally beat Douglas to the other island.
