Elizabeth "Liz" Benton convinces her Research Advisor Sally to research every type of strangers in the social media "The Den" to her project. She has conversation also with her boyfriend Damien Clark, her friends Max and Jenni and her pregnant sister Lynn Benton through The Den while collecting data for her work. Liz does not note that her computer is hacked by a stranger without webcam, and hers records Damien and she while having sex. Out of the blue, the stranger shows a gagged woman being murdered to Liz and she shows the video to Sgt. Tisbert. Although he says that the video appears to be genuine, he tells her that most of them are fake, and he does not have resources to investigate. Liz asks Max to hack the user, but he says that he is probably using VPN making impossible to track him down. Soon Damien, Jenni and Elizabeth are abducted by hooded men and brought to a derelict building in a junkyard. Who are they and why are they so interested in Liz and her friends?—Claudio Carvalho, Rio de Janeiro, Brazil
