Mara Davies, obsessed with true crime, starts a podcast called *Echoes in the Dark* to investigate unsolved mysteries. While researching a series of disappearances of young women with an interest in true crime, she uncovers a disturbing pattern: the killer might be targeting women who dig too deep, including herself. After publishing an episode hinting at a suspect, Mara hears strange noises at her apartment and realizes the killer is after her. He confronts her, leading to a struggle where Mara is overpowered and vanishes. The next morning, a chilling episode of her podcast is uploaded, featuring sounds of a struggle and a sinister message: "This is what happens when you get too close." Mara is never found, and her disappearance becomes another unsolved mystery. Meanwhile, the killer starts his own podcast, telling his story from the shadows.
