When Lange Crawford and her family move to Shady Springs, Pennsylvania, she quickly settles into her new life, which includes a great group of friends, a crush on the songwriter Vaughn, and living in a haunted, 200-year-old farmhouse. Shady Springs also plays host to The Hunt, an infamous murder mystery festival where students solve a--supposedly--fake, gruesome murder scheme during the week of Halloween. During a sance in the farmhouse's creepy barn a few weeks before The Hunt, Lange and Vaughn hear a ghostly whisper begging for help. The mysterious voice leads them to uncover letters and photos left behind by a murdered girl, Ginny, and they become obsessed with her story and the horrifying threats that led to her murder. When they begin receiving the same threats Ginny did, though, it's clear that someone is willing to do whatever it takes to halt their snooping. Will they be able to discover how their own past is connected to Ginny's before they suffer her fate?
