Later, a group of men led by Pogue return to the jail, where they kill all of the guards and get Floyd out. Floyd tells Pogue to get him out so they can get the anti-toxin that the army has brought into town. Floyd's plan was to start the outbreak, then use the anti-toxin on himself. and the anti-toxin Floyd bought along with the NAM37 only slows the NAM37 down instead of being a cure. Wesley takes a sample of Holly's blood, and Floyd is visited in jail by his right hand man and medical expert Nate Pogue, who has also been infected. So far, 94 people have been infected, and the NAM37 has killed 5 people. After buying the NAM37, Floyd infected himself and started the outbreak by spitting on Tomkins. Richard also tells Wesley that a technician working for NAM37's developers stole a big sample of the NAM37 and was detained by security in Billings, Montana, one day after the NAM37 was sold to Floyd, but the technician killed himself before anyone could ask him any questions. Richard tells Wesley that the toxin is a warfare product called NAM37, which is ten times more potent than anthrax. Wesley asks Richard about an anti-toxin, then they go to Tomkins's room, where Tomkins has died. Richard arrives in town and talks to Wesley, who knows that some kind of toxin has been released. Wesley tells Frank to stay in town instead of going to the farm, then Wesley tells Holly to stay where she is, because the town is dealing with an outbreak. Army medical units are sent in, and Ennis is sealed off.

Wesley calls Richard and tells him to send the BRT. Wesley sees a cop collapse, while Tomkins has a seizure.

Wesley is told that Tomkins collapsed in his chambers at the court building. Wesley rushes to the hospital with Holly and tells her to wait in the doctors' lounge, then Wesley is taken to see Tomkins, who looks awful. On their way home, Wesley gets a call on his mobile phone. Holly, like she always does, stops at Wesley's office after school so she can go home with Wesley. After the hearing, Tomkins starts feeling sick. Everyone is shocked when Floyd spits on Judge Tomkins. Floyd has decided to be his own attorney in court. Just over the hill from the farm, a 52 day standoff against militia leader Floyd Chisolm has ended. Wesley and his daughter Holly live on a farm in Ennis, and a farmhand named Frank lives with them. Doctor Wesley McClaren is an immunologist in Ennis, Montana, and he has turned down an offer to join his friend Richard Bach, who lives in Atlanta, Georgia, and is the head of a unit called the Biological Response Team (BRT).
