NBC续订第二季。
When whip-smart Cambodian doctor Thony De La Rosa comes to the United States for medical treatment to save her ailing son, she soon discovers her path won't be as straightforward as she had hoped. As the system quickly fails her, pushing her into hiding, she resolves not to allow herself to be beaten down and marginalized and becomes a cleaning lady for organized crime. Using her cunning and intelligence, Thony forges her own path in the criminal underworld, doing whatever she has to survive.
在这部真实犯罪剧集中，负责调查臭名昭著的连环杀手案的警探们讲述了他们竭力办案的过程，以及其中令人感到痛心和恐惧的细节。
