Dark Places (15)

As a girl, Libby Day is the sole surviving witness of a massacre at the Kansas homestead she shares with her mother Patty and sisters. Libby believes the carnage was the work of a Satanic cult and in court, she testifies against her teenage brother Ben. Thirty years later, Libby encounters a team of amateur investigators called The Kill Club, who are convinced that Ben wasn’t responsible. They convince Libby to work with them to reopen the case and discover the truth about the horrific events that fateful night.
