Sixteen teenagers in their final year at Hengistbury Hall, a prestigious prep school, were going on an adventure, staying on a tropical island on their own without any adults.

Despite certain parents' misgivings, the plan went ahead and with everything packed up, they set off.

They all had their specific tasks mapped out for the days ahead and couldn't wait to experience life on a desert island - especially sunbathing and swimming.

Soon, the teenagers discovered there is more to the idyllic island than they first thought. Although on their own, they had the creepy feeling they were being watched and there was something very odd happening. Rustling in the trees, strange giggling noises, music in the air. What did it all mean?

It surely was going to be an adventure they would remember for the rest of their lives.
