Ghost in the Machine

S4 E1: On the outskirts of Charleston, just steps away from perceived safety, The Mason Clan and the remaining 2nd Mass suddenly find themselves under brutal attack by a new Espheni war machine - and a new, deadly creation unlike anything previously encountered. Divided like chattel and spread to the winds, The Masons must each forge new relationships and abilities to survive. Treva Etienne guest-stars.
