I initially thought that this might be a sequel to a "Scream and Scream" but no - this is just quite a messy production that doesn't really make very good use of the three more genre-established actors at it's disposal. It all follows the investigations of "Insp. Bellaver" (Alfred Marks) who is on the trail of an exsanguinator terrorising London's women. After an entrapment effort that does distinctly awry, that trail leads the police to the home of "Browning" (Vincent Price) whose scientific experiments involve a great vat of acid. Meantime, there is a parallel story going on somewhere in totalitarian Eastern Europe surrounding the activities of the ambitious "Konratz" (Marshall Jones) who is quite successfully murdering his way up the greasy pole - and that's where Peter Cushing (briefly) and Christopher Lee ("Fremont") make their appearances in this meandering and frankly disappointing film. There are a few moments to liven it up: you can rarely go wrong with a decent car chase, but the stars I tuned in to watch feature all to intermittently, and those that do have little to bring to a story that could easily have been condensed into a forty five minute "Tales of the Unexpected". Sorry, but not much to see here.
