Pete Dumond, an accomplished but eccentric movie make-up artist, has been with the studio for decades and is completely devoted to his art, particularly the creation of screen monsters. His world ends abruptly when new management acquires the company and arbitrarily decides that the horror cycle has run its course, and the studio will now concentrate on escapist musicals.?Using a combination of hypnosis and a newly developed chemical formula, Dumond is able to use mind control to compel the young actors playing the teenage Frankenstein and werewolf to exact vengeance for him.
