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! The Doctor, Romana and K9 have found themselves trapped in a temporal war. On Aoris, the past battles the future - and the future fights back! With both sides of the war now capable of time travel, the conflict is about to enter a deadly stage. As the pieces of history lock into place, there is little the Doctor can do. With more Time Tanks moving into combat, the endgame is approaching. The people of Aoris risk extinction at their own hand. Can even the Doctor save the same planet twice in the same day?
