Note: This is an audio soundtrack of the TV story, with linking narration by Caroline John. Not to be confused with the novel reading of the same story, released in 2018. Due to declining sales, the BBC stopped releasing new TV audio soundtracks after this point, until they resumed 3 years later with Horror of Fang Rock.

Seven months after it left the red planet, Mars Probe 7 still hasn’t returned to Earth. The Doctor and Liz Shaw join the investigation as a second capsule, Recovery 7, is sent to discover what has happened. But when it returns, something is terribly wrong with its three astronauts...
The space-suited figures are kidnapped and Brigadier Lethbridge-Stewart leads UNIT in a rescue attempt — whilst Liz finds herself at the mercy of dangerous fanatics. Only a solo space flight by the Doctor can break the deadlock surrounding the crew of Mars Probe 7. Closer to home, however, a deadly fear threatens a catastrophic end for the entire Earth.
Caroline John, who played Liz Shaw in the original episodes, provides linking narration for this exciting seven-part story. In a bonus interview she recalls the making of the TV serial, and her time on Doctor Who in general.
