The year is 1987 and there’s a deadly new narcotic on the streets of London. As part of their investigations the Doctor and his companions Chris and Roz move into the Quadrant, a rundown housing estate. An ancient alien menace has been unleashed, a menace somehow linked to a local gang leader known as The Capper, a charmed young boy called Gabriel and his mother Winnie, the enigmatic Frei Foundation, and Eva Jericho, a woman driven to the brink of madness.

As London descends into an apocalyptic nightmare, the Doctor must uncover the truth about the residents of the Quadrant and a desperate bargain made one dark Christmas Eve.

Based on the original 1996 New Adventures novel by Doctor Who writer and executive producer Russell T Davies.

The edges of space, the far distant future, an era even the Time Lords are not supposed to visit.

Laid claim to by disputing factions of humans and Chelonians, the planet Barclow has become the catalyst for an unusual war. In two hundred years of hostilities not a shot has been fired, and the opposing combatants are the best of friends.

But when the Doctor, Romana and K9 arrive, they discover the peace is not going to last. Something dangerous is happening behind the scenes. An election looms. Bodies are piling up. Tensions are growing. Someone, somewhere is trying to make this well-mannered war very angry indeed.

Only the time-travellers can save the day. But that might be their biggest mistake.
