After the unexpectedly horrible ending of the previous episode, our heroes are stunned for a little while. But not for long. Alastair McBride is spinning outrageous theories and revealing some military secrets. They prove that something terrible, indeed, something most unnatural, is in the water around the island. Tessa Dumont has finally made the radio work but now Michael Hammond and the others don’t want anyone to come to the island, at least not before they find out how the rescues can land safely. David Segarra and Marie St. Claire want to further investigate the city and they go there. But the Russian soldiers are most likely there, so the duo must be very careful.

Meanwhile, Dumont and Hammond talk with the pair of young boys who are also on the island and find out what happened to them. Apparently, they lost their parents in the storm which brought then to the island. However, when St. Claire hears about it, she’s sure that no such accident has occurred in at least five years. How are the boys on the island? Are they lying or is something else going on?

Segarra and St. Claire find out something that changes all their expectations and the episode ends in another tragedy.

Now we find out why nobody leaves. But if nobody can leave, how and why can they come in? If it possible somehow to use that to leave? And can the group talk with the commander of the old Russian submarine and convince him to try? Should they?
