In a quiet Tennessee town, a high school sociology class takes on a mystery that has lingered for decades. Led by teacher Alex Campbell, the students of Elizabethton High School begin investigating the Redhead Murders—a series of unsolved killings that once captured headlines across the South before fading from public memory. What starts as a classroom project soon evolves into a remarkable real-world investigation, as the students uncover new leads, connect long-overlooked clues, and bring fresh attention to victims who were nearly forgotten. Along the way, they discover that the search for answers is about more than solving a case—it's about giving a voice to the people at the center of it and proving that determination can come from the most unexpected places.
