Silvia Hacherman is a successful manager at a chemical laboratory in Rome. Accompanied by her boyfriend Roberto, she visits Afro-Italian friends, including Andy, a university professor, who explains that witchcraft, black magic, and human sacrifice are common in Africa. He reveals that in his country there are still cults that prey on unknowing victims, driving them mad before they are killed. What begins as a seemingly routine trip soon unsettles Silvia as she starts to experience a troubling string of hallucinations and repressed memories.
Dreamlike visions intrude on Silvia’s waking life. She recalls her mother Marta—sitting in a chair and applying perfume in a black dress—as well as a traumatic memory of Marta being raped by a man who later disappeared into the Navy and died at sea. Silvia’s mother died when Silvia was young, apparently by jumping off a balcony. These fragments intrude at intervals, leaking into Silvia’s reality with a stubborn persistence. Interwoven with these visions are seemingly mundane, but oddly out-of-place, possessions: a vase reappears in Silvia’s apartment after vanishing from a local antique shop; a bouquet of flowers dies suddenly; and a mysterious little girl—representing Silvia’s younger self—seems to haunt the rooms.
As the line between reality and illusion grows blurrier, Silvia notices that people around her appear to be plotting something. Neighbors, co-workers, and even service workers cast longer, knowing glances in her direction, feeding a creeping paranoia that she cannot shake. The sense of being watched intensifies when her neighbor and close friend Francesca invites her to a séance, joined by Andy and another neighbor, Mr. Rossetti. At the séance, a blind psychic named Orchidea peers into Silvia’s troubled past and sees her father drowning at sea and Silvia pushing her mother off the balcony. Orchidea also warns that Silvia’s stepfather, Nicola, who once tried to molest her, may pursue her again. Distressed, Silvia storms out, only to discover that Andy, Francesca, and Orchidea are part of a larger, secretive cult. In a tense twist, they converge in an abandoned tunnel, wearing blue lab coats and slipping away from the world as if they belong to another reality.
Silvia’s visions grow more persistent and invasive. The younger version of Silvia seems to take control in moments, nudging her toward violence while Marta’s black dress lingers as a haunting symbol. When Francesca is found dead in her bathtub, the trauma deepens and the cremated remains are left mysteriously in Silvia’s apartment. A chilling sequence follows: Silvia hallucinates pushing Marta off the balcony, then discovers Marta’s black dress in her own bedroom. A box containing the neighbor’s dead cat appears, left by her younger self. Feartightened, Silvia confronts Nicola at her old house, where he corners her and attempts to rape her. In a shock of desperate survival, Silvia strikes him with a concrete block, leaving him on the floor for dead. She tries to show Roberto Nicola’s body, but it has vanished.
The terror accelerates into a night of brutal violence. Silvia’s paranoia erupts into full-blown murder as she breaks into Mr. Rossetti’s apartment and slaughters him with a meat cleaver. She then stabs Roberto, and in a grotesque tableau, arranges their bodies around a dining table in a macabre mock tea party with Rossetti and Nicola. She and her younger self follow each other to the roof, where the girl seizes Silvia and they both fall to the street below, leaving behind the adult Silvia’s lifeless form.
The final, devastating image unfolds in the dark tunnels: Silvia’s naked corpse is laid out on a table in a secluded chamber. A large group of cultists—dressed in the blue lab coats seen earlier—surround her body. Roberto, Nicola, and Mr. Rossetti are among the living participants, and when Roberto cuts her open, the cultists descend on her organs in a ritual feast. After their grisly act, the cultists disappear once more into the tunnels, leaving Silvia’s corpse as the only trace of the ritual.
In this unsettling descent, the boundaries between memory and manipulation vanish, and Silvia’s world is steadily consumed by a terror that seems organized and malevolent rather than purely personal. The interplay between hallucination, real danger, and a hidden, ritualistic network of observant onlookers creates a chilling portrait of a woman whose psyche is pulled into a sinister, underground world.
