Firecracker - S1.E42

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.
