FULL EPISODE SYNOPSIS (spoiler!)

Three weeks have passed since the Robinsons were marooned on the island. Meanwhile Ben and Parsons have moved to one of the outer islands.

Elisabeth is in the forest looking for herbs when the ground is suddenly shaking. Looking up she sees three white goats. At the beach, where the rest of the family is working on the raft to add a cabin and a rudder they feel the shaking of the earth also. David climbs up to higher ground and sees a column of smoke rising from a hill in the distance. It's a volcano.

After having finished the treehouse the family has began to build enclosures for all the animals that they have rescued from the Fury and that Christina has adopted. Elisabeth, by chance, finds out that Emily knows a lot about herbs which can be very useful. Emily tells her that her grandmother was a healer and has taught her that knowlege.

Parsons is worried when he and Ben look through the telescope and discover the raft which seems to be seaworthy. He fears being left behind and that Robinson would escape his revenge. So the old sea dog and Ben row across to the other island. They sneak close to the treehouse, hide and watch.

When the ground shakes again the children also want to look at the volcano and climb to higher ground. Christina sees one of the white goats her mother has seen before. They follow it and are led to a cave. The dog Bruno runs into it. The others follow and discover a little goat kid that has fallen down a small hole and has injured its leg. Exploring the cave further the children find what clearly is a natives's holy chamber. A large carved wooden figure looms in one corner and there is a sarcophagus. Christina sees a black pearl serving as an eye for a carved wooden fish. When she takes the pearl a mechanism is activated and a skeleton rises up from the sarcophagus. Ernst believes the cave to be some kind of a burial chamber. The children leave the cave through the exit of the holy chamber and take the injured animal to their mother who tends its wound.

Unnoticed, a group of natives approaches the island in a large canoe. They arrive just when Ernst is showing the cave to his father. David and Ernst watch how one sick man, who appears to be the chief or king, is brought onto the beach and tended by a shaman. When the natives move towards the entrance of the cave Ernst and David hide behind the large statue. The sick man and the shaman are brought into the cave. The shaman is bound. An angry young man who clearly is in charge leads the native warriors out of the cave again. Outside he discovers a shoe print in the wet sand and becomes suspicious. The natives start searching the forest for intruders.

Meanwhile Ernst and David free the shaman and escape with him and the sick man to the treehouse. Elisabeth and the shaman are both are trying to cure him.

After another argument with David about her refusal to do any chores at all, Emily runs away from the treehouse compound. In the forest she is captured by Parsons and Ben who, in turn, are taken prisoner along with Emily by the native warriors.

The leader of the natives discovers that not only the King and the Shaman have been rescued but that the black pearl is missing too. He questions his prisoners about it. Emily tries to buy her freedom with the knowledge. Parsons realises that if she knows where it is it can only be at the treehouse. So he makes a deal with the leader to exchange Emily for the pearl. Parsons, Ben, the leader and most of the warriors head for the treehouse, leaving only two men behind to guard the girl.

In the meantime the children have followed the white goat once again. From a hill they can see Emily and the native guards. While the girls, Billy and Bruno use the cave's other entrance to get inside and make strange noises to scare away the guards, Ernst goes down to the shore and swims around to rescue Emily. But the guards are not fooled for long and return quickly. The children escape through the cave and the other exit. However, once outside Christina stumbles, falls and hits her forehead on a stone. She is unconscious. The others take her back to the treehouse and arrive just in time to prevent any deal between Parsons and David. The King is finally feeling better. He speaks English and tells the Robinsons that he had been enslaved for many years before he managed to escape. He is suspicious of white people but finally learns to trust the Robinsons.

In the evening the Shaman performs some kind of ritual. The King explains that he is looking for Christina's spirit for she is still unconscious. When Ernst, Joanna, Billy and Emily go to sleep they all find themselves in the same dream with the Shaman. Together they look for Christina in the world of spirits and finally find her in the holy cave. There the spirit of the young native leader, who is the evil brother of the King and also a Shaman, waits for them. He attacks the Shaman. Ernst puts the black pearl into a sling and throws it at the attacker. The native is hit at the forehead and goes down. The Shaman feels that he is dying and urges the children to wake up so their spirits won't get trapped in the spirit world.

At the same time Parsons leads Ben and the other native warriors to the treehouse. Ben manages to steal the musket. The King, David and Elisabeth carry the children to the raft and escape to sea. The Shaman stays behind. The respect his people have for him protects him. The the warriors stop Parsons from even touching the holy man, as they invade the treehouse.

The day is dawning. The children wake up one by one, first of all Christina. Elisabeth is glad to see her well again but is worried about the treehouse. Ernst tells the King about the Shaman's death.

The king's brother has also died. A few warriors signal from the beach and the King tells the Robinsons it is safe to return now. They sail back to shore and walk to the treehouse. Parsons, of course, is not willing to give it up. But again the family gets unexpected help from a white goat that suddenly appears behind Parsons and chases him out of the forest, down the beach and into the water, closely followed by Ben. The family and the King watch and laugh.

The volcano quiets down as the King and his warriors return to their home island. The Robinsons have turned down the King's invitation to follow him to his island because for now this island is their home.
