It's their last summer holiday before Jo and Aaron finish school, and with their parents out of town they don't have much planned for the following weeks. This is until their friend Rudy discovers a mysterious artifact in the abandoned factory in their neighbourhood. Kaea, whom Aaron knows from work seems to know more about it and together the four of them set out to hunt after clues, soon finding themselves in the middle of a quest that seems to have been laid out by a pirate captain.
