Roderick Usher, the ruthless CEO of Fortunato Pharmaceuticals, has spent his life building a corrupt empire alongside his twin sister, Madeline. Their wealth is built on the foundation of Ligodone, a highly addictive painkiller that has claimed countless lives. As the series begins, Roderick is summoned by C. Auguste Dupin, a persistent federal investigator who has spent decades trying to expose the Usher family’s systemic greed and criminal negligence.The narrative shifts between the present, where Roderick recounts his past, and the immediate future, where his six illegitimate children begin dying in increasingly grotesque, inexplicable accidents. Each death is orchestrated by Verna, a mysterious, shape-shifting entity who represents the consequences of a dark pact Roderick and Madeline made decades prior. In their youth, seeking power and immortality, the twins struck a bargain with Verna: they would inherit the world, but their bloodline would be extinguished in a singular, violent collapse before their own natural deaths.As the children—ranging from the hedonistic Perry to the cold-blooded Victorine—perish, the facade of the Usher dynasty crumbles. Roderick, suffering from a degenerative brain condition, experiences terrifying visions of the victims, blurring the lines between reality and his mounting guilt. Madeline, meanwhile, attempts to secure her own legacy by researching a way to cheat death through digital consciousness, leading to a frantic, claustrophobic confrontation between the siblings as the family estate begins to physically disintegrate around them.The climax arrives when Roderick finally confesses his atrocities to Dupin, revealing that he knowingly traded the lives of millions for his own comfort. The siblings retreat to the basement of their
childhood home, a place of deep trauma and long-buried secrets. In a final, macabre act of reckoning, they turn on each other, mirroring the destructive cycle that defined their lives. As the house collapses into a sinkhole, it buries the Usher name and their tainted legacy forever. The story serves as a visceral meditation on
accountability, the corrupting nature of absolute power, and the inescapable truth that every debt, no matter how long deferred, must eventually be paid in full.
