Baron Frankenstein seems to be eccentric man always dreams a super-race. One day, he decides to come back Serbia fullfill an important plan. He builds a desirable female body and he needs a male who is suitable. However, his experiment goes wrong and leads to unexpected consequences.
The film's gross-out climax has the mad-scientist Baron (Udo Kier) screwing his undead Bride on a gurney, then ravaging Marlon Brando with a spot-on parody of Last Tango.
To say that the film is for specialized tastes understates the case. It's simply a gloriously decadent, degenerate joke that you either get, or you don't.
