The Doctor and UNIT are attached to the Inferno project - a top secret drilling operation, which aims to penetrate the Earth's crust and release a major new source of energy. When a toxic liquid leaks from the pipes, the project is thrown into crisis, and when the Doctor finds himself thrown into a parallel universe, the true danger that faces Earth is revealed...

Repeatedly requested on fans' wishlists and repeatedly postponed for technical reasons, this finally appeared on DVD six years into the release run, as the new RSC technique had been perfected with The Claws of Axos.

Cover art by Colin Howard. All photos on the back were in b/w, which seemed to confuse the US copy-writers into claiming the story itself was monochrome.
The episodes were sourced from Canada, who had been accidentally provided with an early edit - a scene with a radio announcement by Jon Pertwee (cut at the last minute by Barry Letts) was therefore included.

Restoration NotesThe Canadian-sourced NTSC 2" Quads were first passed through the RSC system, and then had their luminance and chrominance separated so a higher level of DVNR could be applied to the colour than to the b/w part of the image. Jitter throughout portions of the episodes was then manually corrected and the opening credits sequence recreated digitally in Adobe After Effects. The extra scene (see "VHS" above) was cut back out, using a b/w print as a guide, and a short sequence in episode six suffering from a severe offlock was dropped in from the b/w copy and colourised by hand.
