I always loved the premise of Banshee. An ex-con (Antony Starr) rolled into the small Amish Pennsylvania town of Banshee. He stops into a bar run by Sugar Bates (Frankie Faison). The other customer in the bar is Banshee’s soon-to-be new sheriff Lucas Hood. Their socializing is interrupted by a couple of guys intent on robbing the bar. A fight erupts with the ex-con coming to the aid of the sheriff. When the dust settles only the ex-con and Sugar are left alive. The ex-con sees an opportunity and becomes Lucas Hood.
Fast forward to season four, the final season — Hood has resigned as sheriff and lives in seclusion in a cabin in the woods. Brock, now sheriff, locates Hood and reveals to him that Rebecca Bowman has been murdered, the third girl in town ritually eviscerated by a serial killer. Meanwhile, Kai Proctor, the orignal arch nemesis of Hood, is now the mayor of Banshee.
Proctor sets up a line of business with the Colombian cartel, and shuts down an illicit porn operation Calvin Bunker ran without his knowledge.
With over-the-top violence and move twists than a game Twister, the town of Banshee implodes.
