M036 - The Rapture

A hot new European nightclub called The Rapture draws the Doctor's attention when he and Ace come to Ibetha to relax after their ordeal in Colditz. An angelic DJ and his brother seem to have slipped mind control into the club music. And, at the same time, a mysterious young man has set his sights on Ace for unknown purposes.

Other than a clever introduction via radio personality to the techno remix of the Doctor Who theme music, the episode relies mostly on Ace and her developing storyline while remaining very Earth-bound.
