 The little prince Yubi has arrived on Earth and hides in a barn together with his droid Zax and their new friend - Benji. Yubi s "high-tech" solar-stove, made of umbrella and tin-foil is not working, and his cypher (the cool bracelet on his wrist) says it is time to eat. So Benji and Zax go to find a new reflector. In the town they see Darah and khyber - two hunters from Yubi s planet Anthar who come to Earth to bring Yubi back in jail to his planet. A chase starts, Zax gets broken but the prince gets a help in his escape from a nice old bag lady
