Primal
Presumed dead, a group of undergraduate students who go missing on a deserted Pacific island emerge one year later in two groups of ragged (and naked) survivors. All but one of the surviving women have conceived, and two students, plus their professor, are said to have died.
In the glare of the world's media, every survivor sticks to the same unconvincing version of events. Piece-by-piece the narrator examines the evidence and conducts interviews with the survivors, to work out exactly what happened on the island during that year. Slowly, a disturbing picture emerges of feral humans driven by rivalry and sexual tension ...a 'Lord of the Flies' scenario for adults that suspiciously seems to test the dead professor's theory that by nature people are no different from apes in the wild.
