After recovering from injuries sustained in the mob attack upon himself and his creation, Dr. Frankenstein falls under the 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 without understanding that his intentions are generally good despite his lack of socialization and self-control.

Working in Dr. Cranley's laboratory, scientist Jack Griffin was always given the latitude to conduct some of his own experiments. His sudden departure, however, has Cranley's daughter Flora worried about him. Griffin has taken a room at the nearby Lion's Head Inn, hoping to reverse an experiment he conducted on himself that made him invisible. But the experimental drug has also warped his mind, making him aggressive and dangerous. He's prepared to do whatever it takes to restore his appearance.
