Season 3 - Episode Guide

Simon and Chrissie return to the rendezvous point to meet the others but find only a chilling message from Shona. Harry and Lucy are aghast to meet Helen Stanich, and even more shocked to hear what she has to tell them. Eventually, they decide to go with Stanich to meet a mysterious Professor of Ufology.

Simon, Lucy and Harry are on the run from Stanich and Professor Sharpe. Confused about Chrissie's disappearance, they know that they cannot trust anyone, and need to get to Astrid Island. When they are discovered by Stanich the group are packed off in an ambulance to be sent to the airport and deported.

Now reunited with Gerry, Simon, Lucy and Harry decide that they must try to get to Maracoomba Island. Gerry says this is the mysterious Astrid where they believe that they will find the answer to their friends' disappearance. The group discover their faces on posters all over the area and Simon is recognised and challenged. Is the game up?

The remaining three of the Falkirk group are questioned, but where is Lucy? Simon explores the camp and discovers her in the sick bay. Lucy and Simon are apprehended by the stewards but escape and after eventually discovering the secret purpose of ASTRID Island, they stumble upon a chilling new sighting.

Lucy and Harry realise that if Simon is still in the camp it means that the others who have split and disappeared with red eye are probably still there too. They spot their missing friends playing in a rock pool and realise, as they did with Simon, that something is definitely not right about them.

Lucy despairs as she and Harry feel that they are losing their battle against time. Despite his own doubts Harry urges Lucy on and they escape - only to discover that the stewards have set their own friends to find them. Lying low, Harry spots the small boat he saw before they came to the island and they wade out to meet it.

The appearance of Stanich raises the stakes as the hunt for Harry and Lucy steps up. The encounter with the twins begins to make sense for Harry and Lucy who realise that they have to go back home to before the Aussie UFO trip started to warn their friends of the dangers they now know to be ahead.
