The TARDIS touches down on Nadurniss, a planet under quarantine. A joint Nadurni/human mission has recently landed on the planet to study it for feasible re-colonisation. Two millennia possess passed because the Nadurni Empire fell at the end from the Prokarian Battle, and Nadurniss appears to be a lifeless, barren globe – but a inexplicable illness is infecting the Nadurni, and today the whole group is in peril. The nature of the an infection becomes apparent when the sickest Nadurni dies and an amorphous about Doctor Who: Sleepers In The Dirt creature emerges from its dried-up body. A shambling mound of bacteria, acting as you being – a Prokarian – it has been on earth all along, sleeping in the dirt. As the Prokarians strike, Amy is contaminated. THE PHYSICIAN can do nothing at all to help her – until he realises the fact that cure could lie in the past. He and Rory must travel back again more than 2000 years to try and save her existence… Written specifically for audio by Darren Jones, Sleepers in the Dust features the Doctor, Amy and Rory, as played by Matt Smith, Karen Gillan and Arthur Darvill in the acclaimed hit series from BBC TV.
