A large Providence convoy commanded by Six is transporting a case of unstable nanites through a desert. Rex, Bobo, and Noah are assigned the humiliating task of transporting the force's toilet paper on a beaten-up truck; Rex is further annoyed at not... (more) being allowed to drive. After his attempt to resuscitate the truck's radio backfires and fills the cabin with smoke, the three stray down a side road. Meanwhile, the convoy is ambushed by a criminal gang of self-declared anarchists, led by the deranged cyborg Gatlocke. The gang successfully hijacks the nanite carrier, only to discover that it is a decoy, its actual cargo being toilet paper; the nanite case had been covertly loaded onto Rex's truck. After some misadventures including an unsuccessful snack stop and an attempt to flirt with girls in a convertible, Rex, Bobo, and Noah trace their way back to the convoy route, coming across the aftermath of the ambush and the waiting gang. Gatlocke demands the truck; a short brawl ensues between him and Rex before the three are able to escape with the truck and one of the gang's all-terrain vehicles. After a running Mad Max-style battle, the gang is defeated and Gatlocke falls into a canyon; his cybernetic parts damaged, he climbs out and demands the nanites again when Providence relief forces show up. Six explains that the nanites are now inert; what he had meant by "unstable" was that they were vulnerable to vibration. The turmoil of battle having resulted in their deactivation, they are now useless to either Providence or Gatlocke. An enraged Gatlocke takes a swing at Rex; he is knocked out cold and taken into custody. Rex, Noah, and Bobo get back in the truck, Rex finally being allowed to drive.
