Two astronauts, Harris and  Jefferson with their robot Roland, land on an unknown planet to investigate the source of a radio signal beaming out into space. They are excited since this is the first inhabited planet ever discovered and they speculate about what fantastic new life forms they might find.

​

All they find however is one lone, humanlike inhabitant called Zolo. The eccentric Zolo explains how he left his own busy, noisy planet to seek solitude where he could create great works of art, invent amazing inventions and solve the mysteries of the universe. Unfortunately, when Zolo reveals the results of his efforts, Jefferson and Harris must tell him that they are all things that have already been invented or discovered by others.

​

Zolo realises with dismay that isolating himself from others has not assisted but hindered him. To cheer him up Harris and Jefferson invite Zolo to accompany them in their exploration of the galaxy. He refuses. At that moment, however, they realise that they need to leave the planet as the two moons are aligning and it is their only chance to escape the gravity. Zolo, after much soul searching relents and they set off on a journey into the unknown.
