Two sisters, Dophia and Delia, head out on an adventure. For the first time, their parents have let them explore the island on which they are vacationing. What they are not prepared to come across, however, is the mysterious creature that haunts the island: the Dune Devil. Together, these brave girls must use their wits to escape his clutches and return home. In addition, they find that the Dune Devil may not be so terrible after all. They learn not to judge someone by their appearance, and that understanding and love are a cure for even the scariest of creatures.
