When a man called Parker contacts the Rogue and says he has a method of stopping the Imperium, Zero agrees to meet him. Del is convinced it's a trap and when Vykar shows up, it seems he's right.
It is another time, another galaxy. Two young teenagers, Tag and Gem travel through space, each searching for their missing parents whilst figuring out their identities and place in society. They are befriended by Zero, a mysterious stranger, with no recollection of his past, who takes them under his wing and protects them from aliens, renegade robots and the evil Imperium.
