Do you dare to answer the phone? This call could be the beginning of your worst nightmare…

After a tough week, all Tania Caitlin wants is to spend a quiet, restful evening at home. As she steps out of the shower, she hears her phone ringing. The video call request is from her best friend, Karen Ward. Tania answers the call and the nightmare begins.

Karen is gagged and tied to a chair in her own living room. The deep, hoarse, demonic voice on the other end of the line is clear: if Tania hangs up the phone, if she looks away, she will be next.

Detectives Robert Hunter and Carlos Garcia take on the case. They soon realize they are up against a bloodthirsty hunter who seeks his prey on the streets and social networks — a ruthless killer who mocks his victims and feeds on their fear…
