The Revenge of Frankenstein

In 1860, Baron Victor Frankenstein, sentenced to death, escapes execution by the guillotine by having a priest beheaded and buried in his place, with the aid of one of his followers (the scuffle and substitution takes place offscreen, and is not realized until later). Three years later, Frankenstein, now going by the alias of Doctor Victor Stein, has become a successful physician in Carlsbruck, catering to the wealthy while also attending to the poor in a paupers' hospital. Hans Kleve, a junior member of the medical council, recognises him and blackmails him into allowing him to become his apprentice.
