Big Finish, Companion Chronicles
Fantastic story with Liz Shaw! She is in vault 75-73/Whitehall, where a Mim spaceship is held from when it crashed, many years before. Before Sergeant Benton joined Unit, there was Sgt. Robin Marshall. Liz tells Marshall, the soldier in this vault, the story of the adventure around this spaceship and when it crashed on Earth, many years before. The Third Doctor and Liz investigate the contents of the ship and a Mim battlefleet shows up. And the real chaos begins. The retelling of the story is great and the ending helps push it over the top. This story just feels complete and great in the telling, framing, and retelling. I could listen to this one again for sure!
