The Daleks are advancing, their empire constantly expanding into Earth's space. The Earth forces are resisting the Daleks in every way they can. But the battles rage on across countless solar systems. And now the future of our galaxy hangs in the balance... The Doctor finds himself stranded on board a starship near the front line with a group of ruthless bounty hunters. Earth Command will pay them for every Dalek they kill, every eye stalk they bring back as proof. With the Doctor's help, the bounty hunters achieve the ultimate prize: a Dalek prisoner — intact, powerless, and ready for interrogation. But where the Daleks are involved, nothing is what it seems, and no one is safe. Before long the tables will be turned, and how will the Doctor survive when he becomes a prisoner of the Daleks? Featuring the Doctor as played by David Tennant in the hit BBC Television series.
