Lizzie (Christina Ricci) races to Boston, where Emma (Clea DuVall) has taken refuge in the luxurious home of Adele Trotwood (Michelle Fairley) and family, with whom she has a very special connection. Stunned to find a vastly different Emma than the cherished sister she knew, Lizzie unwittingly leads Bat Masterson (Matthew Le Nevez) and Tom Horn (Chris Bauer) directly into their path. However, the Trotwood family proves to be more than your average Boston Brahmins, posing an unexpected challenge to Bat and Tom. Trying to ease tensions, Emma makes an impetuous sacrifice. Lizzie plumbs the depths of her cunning to set out to ambush the gunslingers, and somehow pull the sister she dearly loves back from the abyss.
