Kinjal and Kiya's dog disappears before their eyes. Then two enormous flying horses appear and insist on taking them to a place they have never heard of: the Sky Kingdom. The horses need their help solving a mystery: why the bees are disappearing, along with the nectar the horses need to survive. The twins must use Kiya's scientific skills and Kinjal's love of books and language to help the horses. Once there, they discover that the disappearance of the bees is more nefarious than they thought.
