An oil tanker approaches the reef near the island of Fleet on a stormy night. In the morning the wreck of a ship is seen on the beach, but it's not the tanker. This ship is old. On the following days and nights people from the wreck appear on the island but they do not acknowledge the residents, and when they wear out their welcome, Callum and Kelly make plans to get rid of them. But the question remains who were they really?
