由詹妮弗·加納領銜主演的雙面女間諜第四季是一部綜合評分2.0的美國電視劇。講述了　　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.  故事雖說平淡，視覺效果也一般，不過角色之間的互動倒是挺自然的。
