It's the year 2050. It's a city with ziprams that screech across the horizon and hyperboards that zoom through the air. Three teenagers - Zeb, Willis and Arizona - are drawn to a new kind of games console and a weird demo game supplied to them by a mysterious stranger named Grimble Dower. It's a game of superior graphics and challenges, and Zeb is soon unable to resist playing. But his growing addiction leads to danger as he becomes steadily drawn into Grimble Dower's dark world called Virtualitee.
