Jeanette (Susanne Lorette) is an exotic dancer who is facially disfigured after a car accident. She is approached by Professor Levin (Alberto Lupo) and his assistant Monique (Franca Parisi) who have developed a ground breaking method to heal skin in their dingy little lab full of rabbits in cages and radiation. The method works but Jeanette, whom Levin has become obsessed with, requires regular treatments. Those treatments need the glands from murdered women. Levin commits these murders after he, for some reason, transforms into a weird looking beast...
A film that makes no sense, scenes end abruptly even mid dialogue and everything about the film is rather shoddy. The film is quite entertaining but mostly because of it's awfulness.
Don't really expect any vampires, the confusing title is referred to in the English dubbed dialogue. The Italian title translates to Seddok the heir of Satan, which makes slightly more sense.
