After enjoying a graduation party on a cruise, an unexpected storm strikes, stranding a group of young friends on an uninhabited island (or so they thought). Before they know it, they are thrown into a whirlwind battle with the pirates of Ghost Island, who have taken over the island for the last 200 years. Who survives?…
