Heart of Orion

The TARDIS intercepts a strange signal, returning the Doctor and Charley to the Garazone System - where once they had a terrifying encounter with the Cybermen, and foiled a bid to change the course of a terrible android-human war.

Now, people are going missing from all over Garazone Central. The Orion War is far from over, and the Doctor and Charley have landed at the heart of it, again!
