Holly presents her unusual theory about the connection between two other mysterious child murders and the Frankie Peterson case. While Ralph remains skeptical, a more receptive Yunis suggests they start looking into Claude, the last person to have contact with Terry. Jeannie's attempt to include Glory in their group of concerned citizens backfires.

Sensing something ominous afoot, Claude reconnects with his brother Seale in Tennessee, while Holly, Ralph, Yunis and Andy follow him in hopes of isolating the evil force and thwarting its next kill. Meanwhile, a family visiting a local cave festival narrowly avoids a dangerous encounter.
