While Daniel attends the Virginia legislature in Williamsburg as Kentucky's representative, Becky and Israel decide to visit the house she recently inherited from an uncle on nearby Oyster Cove. The Boones discovers that the building, even though it was supposed to have a tenant, is vacant. Investigating further Becky discovers a secret passage that leads to a cave under the house that's being used by smugglers. Before she can return to Williamsburg to report the illegal activities on her property, the smugglers capture Becky and her son and prepare them for a watery grave. Daniel tracks his wife and son to the old house and meets with an old salt who tries to convince him that the banging noises coming from beneath the house are nothing but the sounds of a discontented ghost.
