In this eerie and atmospheric tale set during the Victorian era, the story revolves around the actions and discoveries of Professor Emmanuel Hildern. The film opens with Emmanuel, a scientist with a keen interest in ancient relics, meeting a young doctor in what appears to be a cluttered laboratory. Emmanuel confesses that he has uncovered something truly terrifying—a living embodiment of evil, an entity he has mistakenly unleashed upon the world much earlier than expected. He then begins to recount the origins of his dangerous discovery.
In a haunting flashback, Emmanuel recounts his expedition to New Guinea in 1894, where he uncovered an unusually large humanoid skeleton. This was no ordinary find: not only was the skeleton older than other specimens, but it also showcased signs of being more advanced, hinting at the existence of a long-lost civilization or perhaps beings from a bygone era. Emmanuel was eager to make a name for himself, hoping that this groundbreaking discovery would secure him the prestigious Richter Prize. His hopes, however, are quickly marred by tragedy when he learns of his wife’s death—she had been institutionalized at a nearby asylum for years, kept a secret from him. His half-brother, James Hildern, who manages the asylum, reveals that he studied Emmanuel’s wife and intends to publish his findings, hoping to win the same prize. James also informs Emmanuel that support for his expeditions has been withdrawn, adding personal and professional strains to Emmanuel’s life.
Driven by the need to finalize his research amidst personal loss, Emmanuel returns home to analyze his findings further. He discovers that the skeleton’s flesh begins to grow when exposed to water, echoing ancient myths he uncovers from the region—stories about giants awakened by rain, mythologies which suggest that such beings could have been dormant for millennia, hidden beneath layers of earth and erosion. Emmanuel hypothesizes that this skeleton might be an ancient giant, and that its discovery could unlock long-forgotten secrets. It also raises the frightening possibility: perhaps such ancient beings harbored evil, and if so, it could still pose a threat.
Following his intuition, Emmanuel develops a serum from the flesh of the skeleton’s finger, which he carefully extracts during his examination. His experiments include testing the serum on a monkey, which shows promising signs of neutralizing evil. Meanwhile, his daughter, Penelope Hildern, receives tragic news of her mother’s death. Shocked to learn that her mother was alive and had been institutionalized, Penelope experiences an emotional upheaval. Emmanuel, worried that her distress might signal inherited insanity, injects her with his experimental serum.
The consequences are horrifying. The following day, Emmanuel witnesses the monkey turning violent, escaping its cage, and causing chaos in his laboratory. At the same time, Penelope, overwhelmed and confused, leaves her home, heading into the city. There, she begins to act out violently—attacking men at a tavern and ultimately murdering a man in a warehouse, who is revealed to be another asylum escapee. Recognizing her dangerous condition, James's men apprehend Penelope and bring her back to the asylum for evaluation. Tests confirm the presence of Emmanuel’s serum, leading James to realize that Emmanuel may have unwittingly experimented on his own daughter, risking madness and scandal.
James, who is eager to protect his reputation and win the Richter Prize himself, plots to steal Emmanuel’s research and the skeleton. During this theft, the skeleton is exposed to rain, awakening it—an ancient, living creature. When the carriage transporting the skeleton overturns, the now-animated being escapes into the wild. Emmanuel attempts to pursue, but hesitates after noticing a cloaked figure nearby. Returning home, he finds that the skeleton’s fleshy finger has begun to move again. Frightened, Emmanuel throws the finger into the fire, but the creature, now partly fleshy and alive, eventually reappears. It harms Emmanuel by removing one of his fingers but spares his life, leaving him shaken and haunted.
The story then reveals that Emmanuel’s "lab" was actually a cell in the asylum, and he now seems to be an inmate himself. A visiting doctor questions James about his claims, but James dismisses Emmanuel’s story, casting doubt on his insanity. He also scoffs at Emmanuel’s assertions that his brother was involved or that Penelope is truly his daughter. James asserts his authority, suggesting people want to identify with him. Emmanuel, now a broken man, pleads desperately for help, desperately clutching his missing finger—a horrifying reminder of the creature’s attack and his own failed experiments.
Throughout the film, themes of science versus myth, human hubris, and the danger of tampering with ancient and unknown forces are explored. The film creates a tense atmosphere of paranoia and dread, emphasizing that some discoveries are better left undiscovered. As Emmanuel’s revelations unfold, it becomes clear that his obsession and meddling with ancient evil have unleashed a nightmare that threatens to consume everything. The movie leaves viewers pondering the fine line between scientific discovery and the unleashing of primal forces best left undisturbed.
