An unabridged reading of this classic novelisation, predicated on a BBC Television adventure featuring the Third Doctor. A incomprehensible power loss strands the TARDIS on Exxilon, a sinister fog-shrouded alien world. The Doctor fits the survivors of the beleaguered expedition from Globe, while Sarah discovers a inexplicable super-city and becomes a captive of the savage Exxilons. Most severe of most, the Doctor’s best enemies, the Daleks, get there on a magic formula mission of their very own. The Doctor and Sarah must risk their lives time and again in a eager attempt to foil the Daleks and save millions of humans from a horrific plague. Duration: 2 hours 30 minutes approx
