July 1989, in a sleepy Michigan town, high school grad, Nina Laramie, heads out with her friends and is never seen alive again. Months later, her skeleton is found near a remote party spot in the forest. The ME determines Nina has been brutally raped and bludgeoned to death. Fear and anger ripple through this tight-knit community when the case goes cold. 

Thirty years later, Riley St. James, a Detroit PD assigned to Nina’s case, is determined to get her first big cold case win despite having a similar past to the victim. Relying on her investigative prowess and gut instinct, Riley tracks down a witness, who saw Nina Laramie’s murder. But as the truth comes to light, Riley must face the killers who want their secret to stay in the Hole in the Woods. Based on the 1989 true-life murder case of Shannon Siders for Newaygo County, Michigan. After the case went dormant, a Michigan cold case team was formed in 2011 and uncovered new evidence that enabled them to arrest, try, and convict the killers, who were sent to prison for Shannon’s murder in 2015.
