This story was Big Finish explaining how the Lupari got saddled with humanity, and comes up with a cool explanation. The idea of the 'Lupe/Loop' being their homeworld was a very clever idea as well. I think this suffered from a common Big Finish affliction where we're visiting a supposed band of Lupari...and only really hear from four of them. It was very amusing to have K9 treated as the lord and the Doctor and Leela his servants. Always good to give Leela another badass woman to fight too. A good story, but nothing special to me. Tom Baker was on quite good form though!
