When SKUL agent Theo Phantom attacks Rose's friend Bodleian - the world's first artificially intelligent computer - the spies try to stop him, but Bodleian self destructs and Rose is injured in the explosion. Devastated, she is ordered to take leave from MI9. With another computer hack in progress, Carrie and Oscar use Frank's 'Cyber Visualiser' glasses to follow the electrical signal that leads them to Theo Phantom. However, when they catch up with him, Theo Phantom is shocked and denies any involvement with the second attack. As they arrest him, Oscar sees a strange image of another person in the room, but it quickly vanishes. Mr Flatley tries to get Rose involved in organising a project about the history of the school, but she's uninterested until Frank gives Rose a 'neural patch' to help her fall asleep. Afterwards she starts to find herself waking up in unexpected places in the school and begins to find messages about 'Rose and Bodleian' in old school records. She tells Frank about the messages but he thinks that she's just grieving. Meanwhile, the team learn that another computer hack is underway at the Central Court, and with Theo Phantom in custody they know it can't be him. The electrical signals lead them to a woman working in the Court who, just like Theo Phantom, denies any involvement. Oscar once again sees the mysterious figure and when he finally tells Carrie, the two wonder if could it be some kind of electrical being. Suddenly the screens go out in HQ and the face of "Crime" appears, an electrical being who was created in the explosion that destroyed Bodleian and is fixated on evil. Can Rose find a way to bring back Bodleian in time to stop "Crime" and restore order?
