Zak and the crew continue their Civil War investigation with the Battle of Champion Hill. Zak digs deep into the historic soil, which was the site of 6,000 casualties, and follows the trail of evil extending into the surrounding forest.

In the second half of the two-part special, Bagans invites three lucky fans to the museum to further investigate the dark entities. Then, Bagans ups the fear factor with the arrival of the famously haunted doll, Annabelle, who comes with very strict rules: no physical handling, no provoking and a quart of holy water must be on standby in case of possession.
