She's brilliant, beautiful, ruthless and efficient...and now Sam Hunter is on a mission to find out who wants her dead. From Emmy(R)-nominated creator/writer Frank Spotnitz ('Strike Back,' 'The X-Files') comes Season 1 of this one-hour drama series set in the world of international espionage. Melissa George (HBO's 'In Treatment') stars as Sam, a highly skilled operative for an elite private security firm called Byzantium, who narrowly survives an attempt on her life that may have been orchestrated by members of her own team. Returning to work a year later without knowing who to trust, Sam begins a search for the truth that leads her into a vast, complex and dangerous mystery.
