 Reporter Carl Kolchak is back and this time he is on the trail of a serial killer who is targeting dancers in the Seattle area. The strange thing about the killings is the fact that all the victims had some of their spinal fluid drained and that there was rotting flesh found around the victims necks. Soon Kolchak learns that simular killings have been occuring in the Seattle area every twenty-one years for over 100 years. The trail soon leads to Seattle s underground city and he winds up meeting the killer who tells him that he uses the spinal fluid for a elixer which has been keeping him alive. Unfortunately, it only lasts for twenty-one years and after that time period is up he must leave his abode and go looking for fresh victims. It is now up to Kolchak to stop this madman before he takes the elixer.
