'We must destroy life on earth completely. Every living being.'
Arriving on earth in 1975, the Doctor, Jamie and Zoe discover that the component manufacturers International Electromatics has a vice-like grip on the world's technology. When he encounters the firm's company director, the Doctor realises that there is something very odd about Tobias Vaughn...
Brigadier Lethbridge-Stewart is also aware of unusual activity within International Electromatics, and before long UNIT has the help of the Doctor in its investigations.
Vaughn is in fact in alliance with the Cybermen, and together they are masterminding an aggressive invasion of Earth. The ubiquitous IE technology is set to paralyse the planet's population, whilst the sewers of London are being used as a refuge in which the Cyber forces are massing, ready to burst out upon an unsuspecting world.
If the Doctor and his friends are to defeat both Vaughn and the invasion, they must risk life and limb in an adventure of epic proportions.
In an exclusive bonus interview, Frazer Hines — who also narrates this soundtrack adventure — recalls his experiences of playing Jamie in Doctor Who.
Derrick G. Sherwin was script editor of Doctor Who from The Web of Fear to The Mind Robber. He was then producer from The War Games to Spearhead from Space, overseeing the transition from Patrick Troughton's Second Doctor to Jon Pertwee's Third Doctor, the production's conversion from monochrome to colour, and the re-tooling of the series to a one of Earth-bound, present-day adventures.
Sherwin is also an actor, with a several roles on television in the 1950s and 1960s. He made a cameo appearance in Spearhead from Space as a UNIT commissionaire.
His wife, Jane Sherwin, guest starred in his first story as producer, The War Games.
For historical value, this is great. It's the first time UNIT is mentioned, and the company involved in bringing the cybermen to Earth is mentioned in the 10th Doctor episode Rise of the Cybermen. But the story goes nowhere, the Doctor is completely useless, and it's just not a Doctor Who story. It's a military story, a shoot-em-up. The characters make pointless, destructive choices, at one point getting soldiers killed, and there are no consequences or second-thoughts. And it dragged on for 3 1/2 hours. The show's come a long way since this one.
