Tardisode 8

Synopsis
A woman in a suit tells a man, Captain Walker, about a black hole called K37 Gem 5 which is orbited by a planet. The woman asks him to bring back the power source that is keeping the planet in orbit and become the "man who saved the Empire." When asked by Walker about how she found out about it, the woman produces a small book containing alien writing and what appears to be a map. The woman informs him it was found in the "Galis Expedition". Walker then passes the notebook to someone standing behind him. It appears the location Walker needs to go to is on the other side of the galaxy, and the woman informs him that all they have to go on is the map and "local myths", but reassures him that it's superstition, and Walker will have a "top class" ship and crew. Finally the woman wishes Walker luck, and Walker leaves, passing the person he handed the notebook to, an Ood, who simply says "And the Beast will rise from the pit."

Plot
