Carly, a 14 year old girl breaks into The Hive and for some reason Ros is put in charge of her, which she is not too happy about. Beckett is moving into a rather run-down flat which Alex found for him, and his friendship with Ros is rather ‘rocky'. Carly is taken off Ros' hands by a man who turns out to be a baddie after an ancient funeral mask that the Bureau are looking after. He manages to con Carly into stealing the mask and once she realises why they want it, she runs off and hides it. Soon, both Ros and Carly are held prisoner until Carly gives the whereabouts of the mask. They are trapped under a lift. Carly manages to get out and tell Alex and Ed where it is hidden, and they quickly find it.

The Bugs team are called in to investiagte why the crew on board the Searanger, an oil rig, have suddenly gone silent. After investigation, they discover that the team they are with on the oil rig are not the really crew, and they work with the last surviving member, Paul Grey, to stop a satellite falling onto the Earth. Ros finds beckett unconscious in a room, and they are forced to work closely when they are left to do, betrayed by Paul Grey.

The legendary tomb of King Arthur is supposedly at a site, where suddely a lot of people are becoming ill and new owners have stopped all normal work. beckett goes undercover to find out what is going on, and with the help of the others, they discover that the digging for the tomb has unearthed a plague. Alex falls ill with the pague and Ros works at finding her a cure. She is also worried about Beckett, who insists to stay at the site and stop the men from letting more people die and shows for the first time since they split up that she still cares for him.

Some Twin bright sparks decide that the world does not take them seriously enough, and plan to pay back the company that sacked them, years before. Beckett gets caught up in the process and is Beckett-napped (haha), whilst Ros is having a hard time facing up to the fact that ex-boyfriend Channing sold her designs to a new firm. So, she decides to buy them back, with the help of an old friend, who works at a bank. Alex and Adam go to investigate more about the ‘twin geeks'. However, they are trapped in a room, and the temperature is gradually decreasing, so Ed comes to the rescue. Ros goes to find Beckett, who has a little device attached to his wrist that will make a bomb explode just above him, if he walks to far away from it. This bomb is attached to the ceiling by an electromagnet, and Ros releases this and Beckett catches the bomb and has to run around with this. Ed saves Alex and Adam just in time, but gets jealous when she is more concerned about Adam, than thanking him. Beckett

Two baddies (Zephyr and Wymark) create some ‘spiders' that route around networks looking for juicy bits of information that they can use to black mail people in a ‘get rich quick' scheme using something called Catflap. The Bugs team are called in when a man has this happen to him, and they set up a trap to lure the people responsible to them. However, this goes horribly wrong and Zephyr and Wymark end up with what they think is Catflap (actually it is just a fake.) So, they turn to Adam Mosby for help and blackmail him by saying that they will kill Alex if he doesn't get Catflap from The Hive for them. He agrees and gives it to them in the second part. Ros and Ed go to investigate about Zephyr and Wymark, but are caught and forced to make a run for it, to the top of the building. Luckily Ed has some equipment with him and they absailing down the side of the building. But, Ros gets stuck half way down, as she is panicky about getting caught (her glove got caught in the figure of eight)

Ros has yet another brush with death, this time because she was shot in the head by Zephyr. As she fights for her life in hospital throughout the episode, Beckett is desperately trying to find the people (Wymark and Zephyr) who put her there. Zephyr and Wymark end up in the same hospital as there is the new G-5 chip there which they need to gain enough processing power to con a bank into giving the m a few million pounds. Many things interrupt the surgery being performed on Ros (by a rather eccentric surgeon) including a power cut brought on by Wymark shooting the main power cables, leaving it up to Beckett and Ed to put it back to normal (which they manage to do, of course). At the end, Ros wakes up and is OK, and Beckett actually kisses her, putting the hope in everybody's hearts that they are actually going to get back together. However, this vision is quickly destroyed, as after Alex and Adam's wedding, Beckett and Christa are talking together and Christa practically proposes to h
