After disposing of Siringo and Hilliard's dead bodies, both Borden sisters flee from Fall River to hide out in the snow-covered small town of Cumberland, Maine. Six months later, Lizzie has reinvented herself by taking a new name as Annabelle Grimke and a new job as a prim schoolteacher. Emma, traumatized by Siringo's demise at her own hands, sits in a catatonic state at a nearby sanitarium where she is tended to by a not-so-trustworthy doctor who uses Emma for his latest electro-shock therapy. A pair of local murders committed by one of her teenage students jeopardizes Lizzie's new identity, and the sins of Emma's doctor reawaken her. Meanwhile, Siringo's Pinkerton associates, Mr. Horn and Mr. Masterson, travel to Fall River to look for Siringo and pick up Lizzie's trail.
