A recently paroled master thief assumes the identity of Lucas Hood, sheriff-in-waiting of Banshee, Pa. Keeping his history a secret, Lucas befriends boxer-turned-bartender Sugar Bates, and settles into his new life as Banshee’s sheriff. Lucas inadvertently gets tangled up in the rampant corruption of shunned Amish gangster Kai Proctor, while keeping a vigilant eye out for Mr. Rabbit, the New York mob boss who wants revenge against Lucas and former partner and lover Carrie for the jewel heist that landed Lucas in prison.

Lucas’ cover is threatened when Carrie decides to give him over to Rabbit in an effort to protect herself and her family. Meanwhile, a drugstore robbery turns into a full-blown hostage crisis at the high school, with Deva and Mayor Kendall’s wife Janie among those whose lives are imperiled.

In the aftermath of their bloody shootout with Rabbit, Lucas, Carrie and the Banshee Sheriff's Department (BSD) are interrogated by FBI special agent Jim Racine, who metes out punishment that may, or may not, fit the crimes. Meanwhile, Proctor sets his sights on persuading Rebecca to return to his care. As Gordon stews over his wife's betrayal, Deva shows off her resourcefulness after being caught shoplifting in a mall. Later, a straightforward armored-truck robbery turns into a dangerous high-speed chase involving a mysterious motorcycle pursuer.

An illegal search warrant helps Lucas bust Proctor, at a cost. Sharp and his skinheads look for payback against Emmett, testing the limits of the deputy’s patience. Carrie provides the cash for Max’s treatments and takes a small step towards thawing out her relationship with Gordon and Deva. Job finally gets a lead on Rabbit.

Lucas and Carrie steel themselves for a showdown with a vengeful Rabbit and his ruthless soldiers; Rebecca proves her allegiance.
