The investigation into the grisly murders of two nightclub strippers lead Starsky (Paul Michael Glaser) and Hutch (David Soul) to a ballet school run by Rene Nadasy (John Saxon), a brilliant dancer whose career was cut short by a leg injury. Both victims were students in Nadasy's class. The detectives also learn that the instructor is not only pathologically obsessed with the recent death of his beautiful young wife, he's been known to attend meetings of a nearby Satanic cult. Even so, that doesn't necessarily make him a vampire - or does it?
