由詹妮弗·加纳领衔主演的双面女间谍第四季是一部综合评分2.0的美国电视剧。讲述了 Five months later. Sydney quits the CIA and joins a Black Ops unit called "Authorized Personnel Only" alongside Dixon, Jack, Vaughn and... Sloane whom for limited immunity is co-operating with the APO. Meanwhile, the truth Sydney found out in Wittenberg endangers her relationship with Jack, and eventually she reveals the awful truth to Vaughn: about her father having Irina murdered over a year earlier. 故事虽说平淡，视觉效果也一般，不过角色之间的互动倒是挺自然的。
