In 2014, two twelve-year-old girls from Waukesha, Wisconsin, Morgan Geyser and Anissa Weier, lured their friend Payton Leutner into the woods and stabbed her nineteen times. Their motive? To appease Slenderman, a fictional internet entity they believed was real. 

This episode explores the psychological descent of Morgan and Anissa, the dynamics between the three girls, the planning and execution of the attack, and the long road of recovery for Payton. Through careful research and sensitive storytelling, we examine how myth, mental illness, and isolation collided in one of the most disturbing juvenile cases in modern history.
