This Doctor Who story, written by Geoffrey Orme, was first broadcast in four episodes in 1967.
This audio version consists of a digitally remastered soundtrack with linking narration provided by Anneke Wills.
The TARDIS arrives on an extinct volcanic island, beneath which lies a fantastic subterranean world inhabited by the primitive Atlanteans. The Doctor and his companions move from the frying pan to fire when they are rescued, from death at the jaws of hungry sharks, by the mad Professor Zaroff – whose plans involve nothing less than the destruction of the whole world. Ben and Jamie are sent to work in the mines, and Polly looks set to be transformed into a water-breathing Fish Person unless the Doctor can intervene. Will the travellers be able to engineer the revolution which is needed to save Earth?
