Jake, whilst testing out a new land hopper in Australia developed by Skyvault scientists, gets caught up in a dispute between a heavily armed bike gang called the Road Devils, and a small convoy of gypsies. He defends the convoy and later is attacked by the bikers, who are looking for a stolen microchip intended for Doc Terror that one of the gypsies, Mitch took from a power plant and kept for himself. They kidnap Mitch's girlfriend, Cathy, and it's up to the Centurions to rescue her.

In Chicago, a traditional private eye by the name of Gabriel Knight is asked for help by Crystal Kane, to find out who framed her for Zone Dancing-illegal tapping into corporate computers by connecting people's minds into them. Having seen that Crystal was wearing a real droud (the skull plate allowing connection with computers), Knight seeks out Gibson, a former Zone Dancer who tells him about a dancer in the Zone named Neon who is reputed to have stolen data from Skyvault's computers. Meanwhile, Dr. Wu informs the Centurions that Megacorp, the company that designed Skyvault's beaming program, has had the program illegally duplicated by a Zone Dancer, who now has access to Skyvault's beaming files. Ace is sent to Chicago, along with John Thunder, who is specially recalled for the assignment. At Megacorp, Ace and John find Crystal stealing the data and wearing a droud. After escaping from her trap, they return to Skyvault and deduce that whoever stole the beaming program created a beam

The countries of Quisto and Montenegro are close to all out war due to a recent attack on Quisto, apparently by Montenegro forces. The Centurions become involved due to the prospect of war threatening to involve the whole world. Max, Ace and Jake go to Quisto, while John and Rex go to Montenegro, where President Cordano tells them that it was impossible for his country to attack Quisto due to their defenses being run by the Def-3000 computer. John recons a supposedly abandoned Montenegran base, but is attacked and captured, while Rex is also abducted. They find that they are now prisoners of Lady Fang, who is in charge of the Def-3000 and wishes to start a war between the two countries, from which she will make a profit as an arms supplier. John and Rex are left to escape from Lady Fang's clutches, and the other Centurions beam to Montenegro in order to prevent war from breaking out.
