On the outskirts of London, 1855, mortician and funeral director Helena Morrigan struggles with her limited finances and the heavy burdens of her past. Desperate to secure herself, she takes up residence in an aged house closer to the graveyard, closer to the lost souls that sense her torment and are determined to take her place in the mortal world. As she tries to tame and free the ghostly figures around her, she becomes acquainted with the owners of the home, the recently orphaned siblings, Eric, Audrey and Christian Tarter. Yet, the souls she wants to save are on edge as a horrific serial killer runs rampant, giving Helena a boost in business and suspicion. Against her best efforts, Helena is suddenly thrown into a bloody mystery where new and old friendships are tested, innocents are maimed and a horrific family secret that threatens her chance at a peaceful existence and her existence itself.
