No clothes, no shelter, no hope of rescue. How did they survive the dark side of Paradise?

A group of naked and ragged survivors emerges one year after going missing on a field trip to an uninhabited Pacific island. At first each survivor sticks to the same unconvincing version of events. But through one man's determined investigation a nightmarish story emerges of what actually happened on the island - a Lord of the Flies scenario of regression, tribalism, and murder.
