After being jettisoned and abandoned on the corrosive salt flats of planet Ingo by a nefarious former owner, R2-D2 and C-3PO are rescued by new masters -- good-natured speeder racers Jord Dusat and Thall Joben.

While trying to secure a new hyperdrive, Thall, Jord, and the droids stay with Kea and her mother, Demma Moll, on planet Annoo, where they learn Kea is a member of the Rebel Alliance.

After Thall and R2-D2 set off in the White Witch to destroy the Trigon One, C-3PO & Kea are attacked by the Fromm gang.

After being attacked by the Fromms and crash-landing in the Boonta scrapyard, the heroes are befriended and aided by a rickety, ancient droid named Proto One.

After arriving at the mining colonies on planet Tyne's Horky, R2-D2 and C-3PO search for a new master; they put themselves up for auction and are purchased, along with another strange android, by a young miner named Jann Tosh.

Racing against time and pursued by both space pirate Kybo Ren and droid bounty hunter IG-88, ace pilot Jessica Meade transports Mon Julpa, Sollag Den, Jann Tosh, C-3PO and R2-D2 to planet Tammuz-an so the prince can claim his throne.
