In a darkened control room, Eldritch and Brown watch a map on a computer screen. To Brown's concern, the computer selects a school. Eldritch is jubilant: "Nothing in the world can stop me now...!"

It is the night that the children will take home their new Abyss computers - will Eldrich succeed in his plans? As Olivia enters Miss Maitland's classroom, the light fittings explode. Eldritch and Osley follow her in. Across town in the garage, Reet and Thomas fall backwards to the ground away from the computer screen glare. In the control centre, a power surge is detected...

Outside in the playground, one of the schoolchildren accidentally drops his computer. Olivia screams, and rushes out of the car to tend the broken bits of machinery. In the lane Eldritch clutches his head, and consequently Marcie escapes... The pattern is almost complete, Eldrich is so close to his beloved chaos, but there is one small problem with his plans, in the shape of an over-inquisitive little girl...

With Eldrich gone, things should be getting back to normal, right? Well, they would be, if it weren't for the mysterious arrival of Pendragon and the digging up of the school field... Miss Pendragon tells her group of fair-haired followers that their waiting is finally over. She takes a spade and raises it in a ceremonial manner, then drives it into the ground. In response, there is a deep rumble. "The Behemoth awakes!" she declares, exalted...

Thomas and Marcie discover they are not in an ancient tomb but in some form of underground installation. Pendragon, Inga and their workers follow the children underground. Pendragon has been here before - she recalls when the place was alive with activity. She instructs Inga that the boy is important, but the girl is dispensable... Miss Pendragon finds what she has been looking for - the Behemoth. Far from being a monster of legends, however, it transpires that it is far, far worse - it is the ultimate war machine...
