Obsessed scientist Dr. Henry Frankenstein attempts to create life by assembling a creature from deceased body parts. Aided by his loyal misshapen assistant, Fritz, Frankenstein succeeds in animating his monster, but it flees into the countryside and begins to wreak havoc.

After experimenting on himself and becoming invisible, scientist Jack Griffin, now aggressive due to the drug's effects, seeks a way to reverse the experiment at any cost.

After recovering from injuries sustained in the mob attack upon himself and his creation, Dr. Henry Frankenstein falls under control of his former mentor, Dr. Pretorius, who insists the now-chastened doctor resume his experiments in creating new life. Meanwhile, the Monster remains on the run from those who wish to destroy him.

In Victorian era London, the inhabitants of a family home with rented rooms upstairs fear the new lodger is Jack the Ripper.
