She may be new to the government’s most secretive branch, but 28-year-old Annie Walker (Piper Perabo) has the uncanny instincts, tenacity and persistence that could make this girl-next-door a lethal weapon. Although her first mission unexpectedly ends in a hail of bullets, Annie doesn’t get flustered or second-guess her new career path when the Agency unexpectedly promotes her to field operative. If anything, it has made her more determined to be good at her job and see her assignments through.
Auggies Anderson
前任中情局探員Auggie(Christopher Gorham)在一次任務中因意外失明。現在任職於國家防衛部門的科技部門擔任內勤人員。Auggie了解鮮為人知的中情局組織內的複雜內情。Annie 一來，Auggie很快就知道她的聰明伶俐，結為好友，並且盡其所能幫她。他深深了解Annie，因此願意相信她的直覺。他和Annie在本季晉階為戀人，但他們的關係能夠穩定不變嗎？
A former CIA special operative, Auggie (Christopher Gorham) was blinded during a mission. He is now heading up the tech ops department within the DPD. Auggie understands the intricacies of the massive bureaucracy of the CIA in a way that few others do. He immediately picks up on Annie’s intelligence and takes her under his wing to help her navigate the system. He sees Annie for who she really is and because of that, is willing to follow her instincts. This season, Annie and he become lovers, but will their relationship remain stable?
Arthur Campbell
Arthur是中央情報局的國家情報部部長。氣宇非凡，一言九鼎，他生性愛鬥，不管是跟美國的敵人或是和他一樣在情報局工作的妻子Joan鬥嘴吵 架。然而他希望能讓中情局作業有多一點透明度的想法和單位的天性相齟齬。他有他的支持者，雖然大家可能不承認，但並非人人都認同他的想法。他身陷在中情局 鬥爭當中，而一定會有人受到波及被犧牲。
Arthur (Peter Gallagher) is the director of the Clandestine Service Department at the CIA. A regal and imposing presence, he loves a good fight whether it’s with a known enemy of the United States or verbal sparring with his own wife, Joan, who also works at the Agency. But his bid to bring more transparency to the CIA is at odds with the very covert nature of the organization. Arthur has his supporters but not everyone’s on his side, whether they’ll admit to it or not. He’s in for an uphill battle that’s sure to have its casualties.
Joan Campbell
比起其他身處在男性主導的中情局裡，Joan試圖努力往上爬，獲得升遷。為此她努力堅持，下定決心和保持冷靜。她對她的新員工Annie很嚴格，因 為在她身上看到過往的自己，儘管她不承認這點。而Annie也不了解Joan對她冷酷嚴格是因為要保障她的安全，並且能使她成長，成為一名更優秀的情報 員。因為嫁給她的老闆Arthur，她身處一個尷尬位置。維持家庭和工作間的界線對這對夫婦來說永遠是個挑戰，尤其是Joan懷疑丈夫背著她外遇偷吃。
Joan (Kari Matchett) has managed to ascend higher in the CIA than almost any other woman in a male-dominated agency. She’s done it with grit, determination and poise. Joan is hard on Annie, her newest employee, because she sees herself in her. Not that she would ever admit it. And Annie doesn’t realize that Joan’s ferocity comes from a need to protect her, and make her a better agent, not compete with her. Joan is also in the difficult position of being married to her boss, Arthur. Maintaining the boundaries between home and work is a constant challenge for this couple, particularly since Joan suspects that her husband is cheating on her.
