State of Decay

While searching for a way out of E-Space, K-9 locates a sparsely populated planet. Even though the scanners detect the presence of high technology, the population seem to be living a medieval existence. After making contact with the peasants, their mysterious lords and a small group of rebels, the Doctor begins to suspect that there might be a sinister force working behind the scenes. Matters are further complicated after it's revealed that Adric, from Alzarius, has stowed away on the TARDIS. State of Decay is a fairly decent serial. It doesn't feel particularly original but it's well executed and moves at a brisk pace.
