After a series of gruesome murders in Northern Wales, the notorious Wedlock Killer leaves a trail of blood and terror, their signature signature being the removal of a finger before violently ending their victims' lives. The story follows Laurie Wolf, a sharp-witted Steve Johanson, who works as a radio DJ. As reports of a potential new victim spread, Laurie faces personal hurdles when her regular radio show is abruptly canceled, leaving her frustrated and struggling to find a new platform for her voice. On the final day of her show, she reaches her breaking point, openly criticizing the decline of local radio programming and openly defying corporate playlists, which she believes stifle genuine expression.
Her colleague, Ben Evans, suggests they invite a psychic named Carla Zaza to her broadcast in hopes of spicing things up and aggravating her station’s owners. Despite her initial skepticism, Laurie agrees, mainly to cause further trouble for her bosses. Meanwhile, Megan Duffy as Lily plays a key role in the unfolding events, including a subplot involving her interactions with various characters connected to the sinister happenings.
Prior to the broadcast, Kate Komisarczyk, who is communicating with Ben online, causes tension with her boyfriend, Nick Keller. Nick feels uneasy about her online connections, warning her that trusting strangers from the internet might be dangerous. Kate leaves her disabled son, Marek, with a babysitter under the guise of attending the radio program. However, her real intention is more ominous: she drives Nick to a nearby house with the plan of participating in a burglary. Nick, seeking revenge or perhaps driven by desperation, sneaks into a mansion alone, leaving Kate outside as lookout.
While Kate listens to Laurie's controversial interview with Carla, she remains oblivious to the frightening presence of a bloody, battered ghost who appears briefly in her car. Things take a dark turn when she encounters an old man at the mansion, who claims she is trespassing. Kate claims Nick will return soon, but the old man, who is actually Alan, Nick’s father, insists on waiting with her—raising suspicion. As the broadcast continues, Carla detects strange electronic voice phenomena during her séance, hinting at the presence of spirits.
Things escalate when Nick calls Kate, and she exploits the moment to dismiss the old man, claiming Nick is out investigating some escaped farm animals—an intentionally false story to dismiss him. When she leaves to check on her son and her suspicious environment, the old man reveals that he lives in the mansion, deepening her confusion. Moments later, Nick is violently murdered, shattering her already fragile sense of security. The ghost of Sarah, a victim of the Wedlock Killer, makes her presence known during the séance conducted by Carla, revealing that the killer murdered her on a farm and is still at large.
Kate’s discovery of Sarah's body in the mansion triggers an emotional and dangerous confrontation. Alan, mistaken and grieving, accuses Kate of killing his daughter, but before he can act on his rage, the Wedlock Killer surprises everyone and kills Alan. The killer shows shocking familiarity and cruelty by crippling Kate, and then leaves to fetch her son, intending to kill him right before her eyes. Despite her struggles, Kate manages to free herself. She finds her boyfriend, Nick, dying but able to pass her some crucial information—money—which reveals his own involvement in stealing from his family out of desperation.
As the chaos intensifies, Marek is possessed by Sarah’s spirit while listening to the séance broadcast. Driven by this supernatural force, Kate heads to the radio station, where she finds a horrifying scene: everyone except her son Marek and Ben are dead. Ben, who reveals that the show had been recorded and then broadcast from tape, attempts to cover his tracks by eliminating Laurie and Carla, who had begun to suspect his guilt. In a desperate struggle, Kate fights and stabs him, but she is forced to flee as she uncovers that Ben had been orchestrating the murders.
Guided by Sarah’s ghost, Kate locates a room where Ben has tied up Marek. She attempts to rescue him, but Ben, attempting to silence her permanently, knocks her unconscious. When she wakes, she finds herself on the verge of being burned alive by Ben’s arson plan, but Sarah’s ghost appears at a crucial moment. The ghost intimidates Ben just long enough for Kate to grab his lighter and set him ablaze, ending his reign of terror once and for all. With Ben gone, she rushes back to the studio to free her son, while the last words of Laurie play on the tape—a chilling reflection questioning the existence of an afterlife, and ironically contradicting her earlier skepticism about the supernatural.
Throughout the story, themes of redemption, the supernatural, and the dark depths of human desperation intertwine, creating a haunting tale of suspense and horror that leaves viewers questioning what lies beyond death and what truly lurks in the shadows.
