Romana and The Doc join Space Theseus in a Space Labyrinth to help prevent an invasions of Space Minotaurs
A pilot, a co-pilot, and a bunch of people in yellow jumpsuits are jetting across space in a decrepit craft from the Skonnan Empire. Said jumpsuit aficionados are in fact being brought from their home planet of Aneth to be used as tributes to a local deity called the Nimon. The overzealous copilot manages to break the ship, however, and in addition to nearly collapsing themselves into a black hole, his unorthodox manoeuvre sucks in the TARDIS.
Thankfully, the Time Lord Duo are able to repair the damage before it’s too late, but they don’t leave before the copilot speeds off with his tributes and a fresh Gallifreyan hostage, Romana, to sacrifice to the Nimon. So while she must now lead the Aneths through the inevitable labyrinth on Skonnos, Doc must race to catch up with the action.
