A Man named Matias finds a laptop at a cyber café lost-and-found and takes it home. The laptop originally belonged to someone called Norah C. IV. Matias is working with a sign language app for his deaf girlfriend, Amaya. However, Amaya becomes upset because the app only makes it convenient for her to understand him, but not for him to understand her. Matias keeps getting messages on the laptop for Norah from someone named Erica. He logs onto a Skype video call with his friends — Damon, A.J., Lexx, Serena, and Nari— but becomes frustrated when the computer keeps freezing up. Unfriended: Dark Web 2018
Matias discovers that Erica is Norah when she demands her laptop back. He decides to return it to the cyber café, but before he can, he sees a message for Norah about the payment they received for a video. Curious, he converses with the mystery person, Charon68. Matias’ friends watch his actions, and A.J. recognizes that Matias is connected to the dark web. When Charon68 mentions trepanation, a disturbed Matias ends the chat.
Damon realizes that “Norah C.” is “Charon” spelled backward, as Matias begins to find hidden videos on the laptop. He looks up a street address listed in one of them and sees that Erica Dunne went missing from there; the same Erica that Norah was impersonating. Matias receives a video call from Amaya, only to find that it is Norah C., also known as Charon IV, continuing to demand her laptop back, or else he’ll kill Amaya. When Nari tries to call the police, Matias panics and explains that it was all part of an alternate reality game he is developing. His friends are relieved, but Nari remains suspicious. Matias tries to convince Amaya to come over, but she’s still upset with him, believing he doesn’t want to put in the effort to learn sign language for her. Matias promises he will try and convinces her to come over, though Charon IV secretly follows her.
