Following the battle of New Bern, Jericho begins the rebuilding process, while the Cheyenne government shows a particular interest in the town. While the dispute between Jericho and New Bern is being sorted out by the Cheyenne government, Heather returns. Meanwhile, an old friend of Rob comes to Jericho.

Jericho gets ready for a very important visitor from the new Cheyenne government. Meanwhile, Hawkins and Chavez work to find the new leaderships secrets.

Dale returns from trading with news that the Hudson River Virus has crossed the Mississippi River, and when the town's vaccine supply is seized Jake coordinates a retrieval operation. Elsewhere, Hawkins is forced to show part of his hand to Beck.

Hawkins receives a call on from someone who knows who he is, where he is and lets Hawkins know exactly when he'll be caught. Meanwhile, tragedy strikes.

Jake and the Rangers take on Goetz and Ravenwood while a Jericho Ranger makes a choice that will alter his life. Meanwhile, an old friend comes to warn Heather that her loyalties to Major Beck have placed her in serious danger.

Following the Rangers' decision to take justice into their own hands, Major Beck goes to extreme measures to prove he's in complete control of the town, while Hawkins receives a call from Chavez telling him that it's time to transport the bomb.

Jake and Hawkins have one chance to expose the conspiracy behind the Cheyenne government to the independent Texas administration. However, getting there proves to be the most difficult part of their plan.
