Reverend Henry Armitage manages to take control of a cannibalistic group of petty thieves and the remnants of a former US Army unit, integrating them into his pre-existing band of followers, the New Brotherhood Army. The Reverend's forces begin a rampage through the area, culminating in a series of battles with the inhabitants of the Stronghold. Jellison's force prevails with the help of chemical weapons, saving the Stronghold and also defending a nuclear power plant nearby, thus preserving a supply of electric power that is needed to rebuild civilization.
