After a tiring week, Tanya is looking forward to relaxing, but the ringing of the phone interrupts her preparations. In the late class, his best friend Karen wants to talk to him. Tanya accepts the video call, and with this she can say goodbye to her plans for a peaceful evening, because what awaits her at the other end of the line is the nightmare itself.
Karen was attacked and tied to a chair in her own living room. If Tanya interrupts the call or just looks away from the display, her girlfriend will die and she will be the next one - the deep, raspy, demonic voice promises her. In order to be released, the assassin is only waiting for one precise answer: what is Karen's phone number?
This time, LAPD Special Unit detectives Hunter and Garcia are on the trail of a predator who stalks and collects his victims on the streets and social media, harassing them with anonymous messages and thirsting for their terror.
