Scene

A chain of mysterious islands scattered across deep blue waters, each one isolated from the next, each one bearing signs of human presence. The ferry captain gets a radio call after dropping off the last tourists — the island phones have gone dead. By the time he turns back, one island is empty, and another has more people on it than it should. (Unofficial scene description for immersion)
