Meet Hilo, DJ, and Gina! DJ and Gina are two completely ordinary children. But Hilo... is not!

Hilo just fell from the sky and doesn’t know where he came from or what he’s doing on Earth. (Nor does he know why it’s a bad idea to go to school wearing only your underwear.) But—oops—it seems he’s not the only one who landed on our planet!

Will the three of them be able to solve the mystery of Hilo’s past? Will Hilo manage to survive an entire day at school? And are DJ and Gina ready to save the world?
