Description: Having missed another chance at rescue when an airplane passes overhead, the kids begin to build a raft so they can leave the island. With Jason Quinn still hiding out in the caves on the far side of the volcano, Aaron runs away from the village in an attempt to find his brother. Helen, Tony, David and Mark leave the tree house to go after Aaron. Jeremiah has also gone in search of Aaron who has ventured under the volcano. After overhearing the Prime Minister and his men making plans to question Helen about the five children, Anna goes to the village to stand in for her absent friend. In the caves under the volcano, Aaron encounters a hermit who asks him if he is the son of Adam Quinn. The Hermit explains that he and Adam Quinn were prisoners together on Malo. Fleeing from the Hermit, Aaron is rescued by Jeremiah and is soon reunited with Jason. The rest of the kids are close behind and after a short visit, they return home... travelling around the volcano.
