An alien named Kokey from the planet Yekok had crash-landed on Earth in his ship. He eventually befriends a young orphan named Bong, and he helps Kokey to fix his ship so that he could return to planet Yekok. Kokey also befriends other people - Anna, the sister of Bong, Abie, an aspiring pilot who will help build Kokey's ship, and Peping. Meanwhile, Kokey's enemy, Korokoy, followed him to Earth in order to find a crystal (which Kokey values the most). Bong, Anna, Abie & Peping must help Kokey to find the lost crystal, fix his ship in time, and defeat Korokoy.
