Starring Tom Baker as the Fourth Doctor and Louise Jameson as Leela, Doctor Who: The Abandoned is set entirely aboard the TARDIS and features our heroes forced to fight an invasion of their very home!

The Point of Stillness. A place the Time Lords are forbidden to go. It cannot be drawn, it cannot be whispered, it cannot be thought. And yet somebody is very keen to reach it.

Deep within the TARDIS, something unusual is happening. One of the ship's oldest secrets is about to be revealed, and once it is, nothing will ever be the same again.

As danger materialises deep within the ship, spectral strangers lurk in the corridors and bizarre events flood the rooms, someone long-forgotten is ready to reappear. The Doctor and Leela are soon to discover that their home isn't quite the safe stronghold they thought.

Doctor Who: Zygon Hunt concludes series three of The Fourth Doctor Adventures in August, and sees the return of the malevolent aliens who first came to prominence in classic Tom Baker tale Terror of the Zygons. Since then, of course, they've menaced the Tenth and Eleventh Doctors in anniversary special The Day of the Doctor.

On the jungle planet Garros, Earth Forces Knight Commander-in-Chief Greg Saraton and his team are hunting gigantic beasts, for sport. When the Doctor and Leela arrive, they are caught up in a web of intrigue where there is no clear friend or foe.

What is Saraton’s vital connection with Earth’s Solar System’s Defence Shield? Why are the giant reptilian birds of Garros attacking? What terrible secret lurks deep within the trees?

Before the truth can be revealed, a heavy price will be extracted and loyalties will be tested to the limit.
