The Satanic Rites of Dracula. Prominent people in 70s London appear to be involved in some sort of weird cult, much to the alarm of some in the security services. That alarm only grows when it seems the cult are developing an even deadlier strain of the Bubonic Plague, but no one suspects the true evil hiding in the shadows - Count Dracula! Christopher Lee and Peter Cushing are at it again in this mid 70s finale to the Hammer Dracula pictures, which is an odd but very entertaining mix of vampire horror and conspiracy thriller crossed with The Avengers (it's even got a pre-Purdey Joanna Lumley) with a dose of Pertwee-era Doctor Who courtesy of Who scribe Don Houghton (Dracula as the mysterious head of a nefarious corporation with global ambitions is very Delgado Master). This isn't popular with some Hammer fans, apparently, but I found this a thoroughly entertaining romp.
