Steed and Dr Keel return to action in these four recreations of classic lost episodes. 1: "Ashes of Roses". Carol goes undercover at a hairdressing salon, which appears to be at the centre of an arson ring. 2: "Please Don’t Feed the Animals". Steed takes on blackmailers who are extorting secrets from government officials. 3: "The Radioactive Man". Someone is at large in London, unwittingly carrying a radioactive isotope. 4: "Dance with Death". Dr Keel is framed for murder.
To escape a catastrophic volcanic eruption the Doctor takes the TARDIS out of space and time - and into a void he can only describe as 'nowhere'. But the crisis is far from over and when the time-machine's circuits overload, the TARDIS explodes. The Doctor, Jamie and Zoe come to in a dark unearthly forest. There they encounter a host of characters who seem somehow familiar.
