Emily Kane arrives at her sister Carrie’s house to find the front door unlocked, dinner on the table, and the family nowhere to be found—Carrie, her husband, and two daughters have disappeared. When the police turn up no leads, Emily turns to her former boyfriend David Raker, a missing persons investigator, to track the family down. As Raker pursues the case, he discovers evidence of a sinister cover-up, decades in the making and with a long trail of bodies behind it.
