Holly, Zach and Kevin can't wait for the last day of school to finally end so they can start their summer vacation. They had been planning for weeks to camp out in Holly and Kevin's backyard. Each summer these three cousins would build forts out of the old driftwood that would wash up on shore. This year they had built the best fort ever. What seemed to be a great start to their summer vacation soon turns tragic as these three young teens find themselves lost at sea with no help in sight. But just when the O'Malley kids think things couldn't get any worse they shipwreck on a strange and mysterious island. This uncharted island is not like any of the islands they have seen back home in the Florida Keys. Once on shore they begin to search the island for help. But instead of finding help they encounter strange and unimaginable things that will terrorize them. One by one they will have to face their own fears as they fight to survive. Should they survive they will have an adventure of a lifetime.
