Description: Helgoland. Here, on Germany's only offshore island, a small community of survivors of an apocalypse that has overrun the rest of the world and plunged it into chaos is holed up. But the price of their survival is high. The resources on the rocky island are scarce, so that an inhumane "social ranking" system determines the lives of the 513 inhabitants: each islander is evaluated according to his usefulness. The only doctor is high on the list, others are far behind, and they have to fight for their place on the list and their survival. Meanwhile, people from the mainland are trying to get to Helgoland and the Helgolanders have to defend their island.
