Mary Shelley returns from the afterlife to tell a story she never finished, and she does so by possessing a woman named Ida in 1936 Chicago. Through Ida’s traces of memory and voice, the tale unfolds with a somber, almost mythic cadence: Shelley speaks of the criminal world around crime boss Lupino, whose henchmen, Clyde and James, quietly whisk Ida aside as the author’s tirades spill out, causing her to stumble to her death on a staircase. In this same city, a different drama takes shape around the revived dead and the endless ache of loneliness.
In another corner of Chicago, the Frankenstein creature—often called Frank—arrives at the doorstep of scientist Dr. Cornelia Euphronius. Frank, having learned from the old legends of reanimation, asks Euphronius to create a companion for him after more than a century of solitude. Together they select Ida’s corpse and succeed in reviving her, though the process steals Ida’s memory in the process. Frank seizes on this amnesia, presenting her as his bride and insisting that her lost memories are the accident that fractured her past.
Ida’s revived life begins with a shared night out: they attend a screening featuring Frank’s favorite actor, Ronnie Reed, and later dance in a club. A brutal turn comes when two men try to assault Ida; Frank kills them and, despite her pleas to be left behind, she chooses to flee with him. The couple slips away on a train bound for New York City, during which they murder a security officer who confronts them following Shelley’s destabilizing outburst. On the other side of the country, Detective Jake Wiles and his assistant Myrna Malloy start to connect a string of murders and disappearances to the lovers’ trail.
The fugitives land in New York, where, in a new identity, Frank tells Ida her name is Penelope Rogers. The alias is not enough to quiet the escalating chaos: at a screening of Revolt of the Zombies and later at a high-society party, Penelope disrupts the crowd with a fierce energy that crosses into mayhem. Frank participates in the revelry, even dancing as Reed does in his films, while partygoers fall under a strange, Shelley-possessed influence. When the police arrive, Penelope resists and holds Reed at gunpoint, condemning the men in attendance for abusing women. Detective Wiles recognizes her true identity as Ida, and the couple’s escape becomes a headline-grabbing spree that ends with a stolen car carrying them out of the city.
As Lupino notices the sensational crimes in the press, he orders harsher measures, executing James for failing to quiet Penelope and sending Clyde to finish the job. Malloy’s investigation—connecting sightings of the couple to films set in Ronnie Reed’s worlds—drives them toward Niagara Falls, where Wiles confronts Penelope and informs her of her true past. A tense moment leaves Wiles injured when Penelope shoots his foot, forcing the couple to flee again. They take shelter at a drive-in where Frank hints at the truth of their origins, prompting a moral reckoning in their fragile bond.
Wiles’s confession to Malloy—that he and Ida had once planned to take down Lupino but failed—introduces guilt into the pursuit. Malloy rises to replace the retiring Wiles, and the couple’s path converges with the law again at the drive-in. Frank seeks Penelope’s forgiveness, reaffirming his love for her, and she reclaims the identity of the Bride as they prepare for one final turn of events. In a brutal twist, Clyde shoots Frank, and the Bride escapes with his lifeless body back toward Euphronius’s laboratory, pursued by Malloy.
Euphronius herself refuses to reanimate the dead again after a traumatic attempt to save her husband, a decision that blocks the pair’s earlier fate. Clyde presses into the laboratory and fatally shoots the Bride, leaving Euphronius alone with the Bride’s and Frank’s corpses. Malloy arrives and orders the search for Clyde as the police take control of the scene; a glimmering sense of possibility returns as Malloy and the revived influence of Mary Shelley—who guides Euphronius—encourage a new experiment. Euphronius, moved by their voices, decides to attempt one final revival of the couple.
Clyde is soon captured by police, and the lab fills with the sign of something extraordinary: bright lights spill from the laboratory as the revived bodies of Penelope and Frank hold hands once more. In the ending credits, Lupino is finally apprehended by Wiles, while female rioters inspired by the Bride fill the streets, closing the tale on a note of renewed energy and eerie triumph.
- This retelling preserves the film’s core arc: a supernatural intercession by Mary Shelley, the revival and trauma of Ida, the creation of Penelope, a relentless crime spree, uneasy confrontations with law enforcement, and a final, ominous revival that hints at a cycle renewed. The story stays faithful to its themes of memory, identity, power, and the perilous lure of reanimation, while delivering a richly detailed journey through love, murder, law, and the uncanny certainty that some corpses never stay buried.
