This range of two-part audio dramas stars Tom Baker reprising his most popular role as the Fourth Doctor (from 1974 - 1981)with
a number of his original TV companions. This fifth series reunites the Doctor with Romana (Lalla Ward), a fellow Time Lord
for adventures across Time and Space! In the control room of a World War 2 submarine something strange has started to happen.
As the ship runs out of control, its crew begin to fall unconscious. Finding the submarine in the last place they'd have expected,
the Doctor and Romana are confronted by a mystery. Once fully populated, there are now only three men on board. And there's
now also a chimpanzee. What has happened to the rest of the crew? What are the strange noises they can hear outside the hull?
And most importantly, who, or what, is Dethras? CAST: Tom Baker (The Doctor), Lalla Ward (Romana), Alistair Petrie (John),
