The Revenge of Frankenstein

Baron Frankenstein must be executed. But he makes a deal with the executioner and a priest is executed instead.

Frankenstein flees to Karlsbruck and continues his experiments there under the name of Dr. Stein. As a cover, he uses the image of a fashionable doctor for the rich and opens a practice in a hospital for the poor. Together with his semi-paralyzed assistant Karl and the young doctor Hans Kleve, burning with a thirst for knowledge, he again conducts experiments on reviving bodies and their parts.

Hoping to get rid of suffering, Karl asks to transplant his brain into a new body that previously belonged to the grave digger. Karl's brain allows scientists to hope that this time they will be able to create the perfect artificial human. The operation is successful, but problems soon begin: the brain of the "renewed" Karl is injured, and he is again partially paralyzed. He becomes aggressive, escapes from the lab and starts killing people.

In an attempt to find Karl, Frankenstein and Kleve come to the ball to the mother of one of the rich patients, Countess Margarita. At the same time, Karl, who has turned into a monster, breaks in there, who exposes the baron, calling him by his real name. Patients who have found out the truth about their doctor brutally, almost to death, beat him. Gathering his last strength, Frankenstein says to Kleve: "You know what to do..." He transplants his brain into a pre-prepared body that looks very similar to the old one.

Taking the name of Dr. Frank, the "renewed" Frankenstein moves to London.
