All families have secrets. But some secrets are deadly. Erika Cass has a perfect family and a perfect life. Until, one quiet evening, two detectives show up at her front door. "Mrs. Cass, we were hoping your son could answer a few questions about the girl who disappeared last night..." A high school girl has vanished from their quiet neighborhood, and the police suspect the worst. Erika's teenage son, Liam, was the last person to see the girl alive. Erika has always sensed something… different in her seemingly perfect oldest child. He's charming, smart, and popular, but mothers have the best instincts, and Erika knows there's more to her son than meets the eye. She wants to believe he's innocent, but as the evidence mounts, she can't deny the truth―Liam may have done the unthinkable.
