When Boss Zukko collects the bounty on Torbin Zixx by handing him over to an unscrupulous criminal kingpin, the Turtles get suckered into mounting a rescue mission. But Zukko keeps capturing Zixx again and again, turning Zixx over to different gangs of thugs, aliens, and crime syndicates and the Turtles keep having to spring Zixx. Discovering that Zixx and Zukko have been working together since the very beginning, collecting and splitting millions of credits from all of the bounties on Zixx's head, the Turtles must teach the duo a (hopefully painful) lesson.
