Ros, Ed and Beckett's first customer appears in the form of Irene Campell, who turns out to have conned Beckett into helping her continue doing her business. Roland Blatty, a friend of Ros' who own the new Bureau of Weapons is trying to put a stop to the devices Irene sells, which have killed countless people. The team race against time to stop Irene and her legal adviser, Morasco and at the same time save Ed from a microbe that is killing him.

Cassandra and ‘Daddy' strike a deal with Jean-Daniel and Ros ends up getting kidnapped by him. Roland Blatty has a ‘brush with death' when he is left in a room filled with lots of ticking bombs. Ed and Beckett go to save Ros, and end up having to use a chain saw to free her as she was handcuffed to a steering wheel, and inside the car there was a hand grenade. Beckett spends the final scene, sawing the steering wheel, to free Ros' wrists, and Jean- Daniel returns to the Bactrian Kings tombs to retrieve the Niobian 5 that was left there.

A deadly powerful creature called Cyberax has escaped from a computer and then suddenly Cyberax the company is born, by no other than Jean-Daniel. He creates a machine that takes over some of the user's mind. Once they have finnished using the Cyberax headset, it leaves a little bit of itself behind. when the person finds out about Cyberax again, as they forget all memories to do with Cyberax, their brains go into overload and they kill themselves. Roland Blatty (the old bureau chief) gets hold of one of these headsets and blows his brain up when Ed jokingly says that he hopes that Roland has had the system checked for viruses. The whole Bureau team are also wiped out when they too discover the deadly truth about Cyberax. Beckett decides that the only way to stop this is to pretend that he has used the headset and had his brain blown up (so to speak) and he is taken away by Cassandra, who is now working with Jean-Daniel. Jean-Daniel realises that Beckett wouldn't do something so stupid

Another second parter to end the Series. Cyberax's destructive nature has entered Ros' brain and Beckett and Ed find themselves racing against time (and the fact that if Ros finds out about the true nature of Cyberax, her mind will explode) to save her. Beckett ‘foils' Jean-Daniel's plans, but in the process accidentally tells Ros the truth about Cyberax, and Ed has to kill her, electrocuting her. The reason being that ‘because Cyberax is a virus in the memory, you have to shut down the system and reboot with a completely new set of instructions'- (as said by Ed).

Roland Blatty is still in hospital and a nurse explains to a new one that he will remain that way forever. However, once she has left the room, leaving the new nurse and Roland alone, he suddenly wakes up and attacks her, before walking out of the hospital. Beckett, Ed and Alex go to check on the other two members of the bureau, who are also in hospital. Ed and Alex find that the woman they were going to check on has also escaped from the hospital she was in, in the same circumstances as Roland. The woman Beckett checks on is, however, still unconscious, and he is explaining to the nurse what to look out for, when the woman wakes up, attacks Beckett and flees from the hospital before anyone can stop her. The team soon find out that the old bureau members are after the four discs that make up the remains of Cyberax. The virus was kept on four discs so that the next time something like that happened, they could use Cyberax to help them overcome it. Beckett is suddenly kidnapped by Rolan
