Tom Baker is to return as the Doctor for a set of BBC Radio 4 Extra audio dramas.
The six-part series, which was produced by Big Finish Productions and recorded in 2012, will be broadcast for the first time later this month.
Featuring a full voice cast, the first episode is titled 'Destination: Nerva', and sees the Doctor and Leela (played by Tenko's Louise Jameson) investigating an alien distress call that appears to be coming from Victorian England.
Their journey through time and space takes them to the newly built Space Dock Nerva, and sets in motion a homecoming that could put an end to the human race.
Nerva served as a location in the 1975 Doctor Who television episode 'Ark in Space', which inspired writer and director Nicholas Briggs to explore the setting further.
The BBC has also teased further adventures in the audio series, including a TARDIS trip to a museum of everything, a possible encounter with Boudica and a visit to London that takes place during a future energy crisis.
What to Read Next
The series is said to conclude with "a showdown with some old enemies" - could we perhaps be hearing the infamous cry of "Exterminate!" ringing out across the airwaves?
The production marks the first time Baker has played the current Doctor since he left the television series back in 1981.
The new series of Doctor Who will air on BBC One this autumn.
