London's Docklands, 1984. Why are uniformed policemen gunning down strangely-dressed vagrants in broad daylight? A prison ship in the far future - who is the sole prisoner aboard the craft? And why are these two locations linked by the time corridor the TARDIS has been sucked into? Lytton's men revive Davros as the Doctor fights off the Dalek in the warehouse. But alliances are shifting with each passing moment. Can anyone be trusted?
