Ever since he had his brain tumour removed, Sam Steyn suffers from a recurring nightmare, a nightmare he fears he will have for the rest of his life. When he is invited to join his friends on a yacht cruise to a private island in the Seychelles, he decides to take up the opportunity as a means to find a way to come to terms with his nightmare.
After a night of partying on the yacht, Sam and his friends wake up one morning to find themselves stranded on the island with little memory of what happened to them.
They soon discover that the island is not what it seems to be. They are not alone. They are being watched.
