When she meets cousins from her grandfather's other family, they're everything she'd hoped for—until it all goes to hell.

Susan’s dreams are shattered when she learns her relatives’ dangerous history, and she is bombarded with threatening messages and sexually explicit content. When dozens more people contact her, Susan realizes she's stumbled into a real-life horror movie.

As Susan desperately search for the truth, she struggles to determine who's an ally and who wants her dead, Susan falls down a digital rabbit hole of career criminals, predators, and sexual cultists in the tristate area.

Twenty years after events took place, this real-life thriller from the dawn of the internet serves as a shocking cautionary tale about survival and perseverance against all odds. Hear Susan’s story in her own words, with contributions from expert guests and the FBI special agent and US attorney on Susan’s case.
