Doctor Who: Galaxy 4

Following the Doctor's regeneration into a new, younger body, the TARDIS lands at an Earth colony on the planet Vulcan in the far future. Mistaken for an official Earth Examiner, the Doctor discovers that a scientist called Lesterson is attempting to reactivate two inanimate, subservient Daleks found in a crashed space rocket. The colonists refuse to heed the Doctor's dire warnings that the Daleks are dangerous.

The Daleks draft the Second Doctor into distilling the Human Factor. Once implanted, it will make the Dalek race invincible. Jamie’s faith in the Doctor is stretched to the limit as the Doctor appears to be collaborating with the Daleks. The Doctor has a few tricks up his sleeve, but then again so might the Daleks.

While the Doctor plays the Trilogic Game, Steven and Dodo are forced to play seemingly childish but ultimately dangerous games with the aim of being reunited and getting back to the Tardis. This brand new animated version has been created using the original audio recordings.

Following the death of Sarah-Jane Smith, her friends and allies reunite at a memorial service to pay their respects.

The original 1967 master recordings of ‘The Macra Terror’ were lost soon after the programme’s original transmission. However, audio-only recordings have survived and have been used here to create a brand new fully animated reconstruction of this lost classic.
