The Agency has got its hands on the Intraneuronal 3000, the largest artificial brain ever created. To put the finishing touches on the programming started by Gabriel Lobe, the notorious computer scientist who is still on the run, Billy and Jon have to take a virtual trip aboard this artificial brain. To do this, they have to connect their consciousness to the machine and not worry about whether or not things are real . . . If the adventure were to go wrong, their consciousness would disappear forever.
