Thirteen-year-old Lauryn thought the cruel texts about her and her boyfriend were just another case of teenage cyberbullying. But the messages didn’t stop. They escalated, becoming more vicious, graphic, and relentless. Everyone had a theory. Parents blamed classmates. Teachers suspected students. Police hit dead ends. Then a digital breadcrumb buried deep in the texts exposed the last person anyone expected.

From Netflix and the director of “Abducted in Plain Sight” comes “Unknown Number: A High School Catfish,” a chilling dive into digital deception. Teen victims, shattered families, and stunned investigators retrace the damage. We also hear from the catfish, allowing the audience to draw their own conclusions about their actions and motives.

OUR SPOILER-FREE REVIEWS OF "UNKNOWN NUMBER" BEGIN IN THE FINAL 13 MINUTES OF THE EPISODE.
