D.J. and his friend Gina are totally normal kids. Until a mysterious boy comes crashing down from the sky and nearly blows up their club house!

Hilo doesn't know where he came from, or what he's doing on Earth (or why going to school in only your underwear is a bad idea!) but he's starting to think he might not be the only alien to have crash-landed on our planet.

Can the trio unlock the secrets of his past? Can Hilo survive a day at school? And are D.J. and Gina ready to save the world?
