On this island, not only nature is murderous.
A dream comes true for Maddy as she takes part in a novel television experiment in which eight strangers must survive on a deserted Scottish island for a year with minimal equipment and incommunicado.
18 months later, Maddy's dream has turned into a nightmare. The authorities pick up the young woman in a fishing village on the mainland. Desperate, she reports how the boat that was supposed to pick up the participants after a year did not come. And how in the following weeks one after the other died, not from hunger or disease, but from human hands. But what is Maddy hiding? And how did she manage to get off the island alive?
