Peggy, Jennifer, and Nadine are three smart, middle-aged women who have discovered they have some “special” skills. Nicknamed the “Murder Posse,” they are members of their town’s murder mystery book club and enjoy helping solve cold cases for amateur sleuthing websites.
After their success solving a cold case, the Posse is getting some respect from town law enforcement who ask them to assist on a new crime that hits close to home. As they learn more about their paranormal skills, the women feel a responsibility to help solve the mystery, but will their involvement lead them into unexpected darkness and danger?
