New Bern is a city near Jericho. The town manager is Phil Constantino, who is also the sheriff. New Bern's land is mostly clay, so its citizens have no way of growing crops. After the attacks, New Bern asks for ten percent of Jericho's spring crop, along with salt, in exchange for ten wind turbines. Ten Jericho men are taken to New Bern to help make the turbines, a gesture interpreted by Jericho's mayor, Gray Anderson, as a passive hostage-taking as collateral for Jericho's fulfilling its part of the deal.
When all but one (Eric Green), plus a citizen present in New Bern previously (Heather Lisinski), of the Jericho citizens suddenly return from New Bern with the generators, Jake Green and Robert Hawkins, go to New Bern to look for the missing people. There they discover that New Bern's leaders are planning a military-style attack on Jericho, having converted their factory into a munitions plant. Many buildings in the town, including the city hall, were heavily damaged by the Ravenwood paramilitary group, an attack residents blame on Jericho's having successfully repelled Ravenwood some time earlier. Residents have been told that Jericho is hoarding supplies.
