A spaceship salvage team drags the TARDIS on board, sending its systems into meltdown.
As the Doctor marshals the motley salvage crew outside, he realises Clara is still trapped within his malfunctioning ship, pursued by a dangerous group of ossified monsters. He has just 30 minutes to find Clara and save his TARDIS before it self-destructs.
