After completing his 15 year prison sentence, an ex-con tracks down his former partner, now known as Carrie Hopewell, in Banshee County Pennsylvania who it turns out is now married to the local DA and has two children. He takes her at her word when she says she doesn't have any of the cash they stole. Later at a roadside bar, he meets the county's new Sheriff, Lucas Hood who has literally just arrived in town and has yet to meet anyone. When Hood is killed during an attempted robbery, the ex-con assumes his identity. The town's youthful mayor wanted to bring in an outsider as Sheriff to deal with their local power broker, Kai Proctor, who seems to have everyone else in his pocket.

Kai Proctor begins the process of co-opting Sheriff Hood but Lucas isn't biting. Lucas continues to build his cover and Job confirms that the real Lucas Hood has few friends or relatives who may blow his cover. Siobhan Kelly realizes that Lucas seems to know little about police procedures. Carrie Hopewell's daughter Deva is definitely getting in with the wrong crowd. Hanson has organized a rave in a vacant barn without Proctor's knowledge. The police raid the rave - the sole purpose of which is to sell drugs to teenagers - but Lucas' approach to shutting it down is somewhat unconventional. Proctor has his own way of dealing with Hanson.

Lucas sets off an alarm while trying to steal a painting from the Harrisburg State Museum. He contacts Job to help him break out. After getting video proof that Proctor killed Hanson, Lucas arrests him. However, the Moody's get in the way.

A motorcycle gang invades Banshee. They attack Carrie and Sugar at the town Spirit Festival. The killing of one of the bikers by Deputy Kelly during the attack triggers a chain of violent events.

The fallout from the rescue of Sheriff Lucas is at hand. Special Agent Racine is in town to investigate. He holds a hearing for all involved. Carrie is not allowed to see her children. Job, Lucas, Sugar, and Carrie rob an armored truck.

Carrie Hopewell has her trial. She is sentenced to 30 days in prison. DA Hopewell does nothing to help. Tensions between the Longshadow's and Proctor's intensify. Deputy Kelly's abusive ex-husband returns to town with extreme consequences.

With Rabbit dead and Emmet's death avenged, Banshee has since been nothing but a quiet town. But things begin to change when Hood eyes a risky new job, as Chayton returns railing the Kinaho to war.

Hood and Brock track down Chayton to Louisiana. Rebecca makes new enemies for her uncle. Colonel Stowe prepares his revenge for the robbery at the base.
