Beneath the dark streets of London they played a dangerous game with trains. Now it is their only chance for survival….
Britain in 2075 is a dangerous place. A man known only as the Governor rules the country with an iron hand, but within the towering perimeter walls of London Greater Urban Area anarchy spreads unchecked through the streets.
In the abandoned London Underground station of St. Cannerwells, a group of misfits calling themselves the Tube Riders seek to forget the chaos by playing a dangerous game with trains. Marta is their leader, a girl haunted by her brother's disappearance. Of the others, Paul lives only to protect his little brother, Owen, while Simon is trying to hold on to his relationship with Jess, daughter of a government official. Guarding them all is Switch, a man with a flickering eye and a faster knife, who cares only about preserving the legacy of the Tube Riders. Together, they are family.
Everything changes the day they are attacked by a rival gang. While escaping, they witness an event that could bring war down on Mega Britain. Suddenly they are fleeing for their lives, pursued not only by their rivals, but by the brutal Department of Civil Affairs, government killing machines known as Huntsmen, and finally by the inhuman Governor himself.
