The second season of the anthology series will feature a new cast and a storyline that draws inspiration from a story collected from the Brothers Grimm, The Singing Bone, as well as real-life murder cases. This season of Sacred Lies follows Elsie as she searches for the family she never knew after being abandoned as a child. The search leads her to her father, Peter, an inmate who may be guilty of more than the crimes he's currently incarcerated for and Harper, a telemarketer turned arm-chair detective with an obsessive hobby of searching for unidentified murder victims.
