After Mike, Pi, Bec, Marcello and Ram all receive a coded message on the Net, they set about decoding it. Once decoded all the kids find themselves meeting Alexander 'Alex' Davis who is the head of Catalyst a new software company.
She offers them all an after school job, testing out the new video games, however Ram (who Alex thought was older) is too young and isn't aloud to stay.
The job begins and the kids meet Virgil, an interesting AI loose on the system.
