在别人眼中，Foster医生有着令人羡慕的一切，工作受人尊敬，家庭幸福和睦，夫妻恩爱甜蜜，孩子乖巧听话。其实她自己也一直这样认为，直到有一天，一支唇膏，一根金发的出现，让她开始怀疑眼前的一切。为了查清楚丈夫是否真的出轨，她甚至利用病人帮她跟踪丈夫，结果却发现事情的真相，完全在她的预料之外。

Louis immerses himself in the world of Ohio’s State Psychiatric Hospitals, meeting patients who have committed crimes - at times horrifically violent - while in the grip of severe mental illness.
They have been found Not Guilty by Reason of Insanity and ordered by the courts to secure psychiatric facilities to receive the treatment it is hoped will one day lead to their reintegration back into society.
Over the course of these two films Louis explores the nature of mental illness. He spends time with the small subsection of sufferers who have found themselves on the wrong side of the law and bears witness to the extremes of the human condition and experience in an attempt to understand how society cares for some of its most vulnerable and most dangerous members.
In the first episode of this two part series, Louis spends time with patients attempting to come to terms with their crimes and the clinicians entrusted with helping to make them safe. And he investigates the difficult question - when is a patient with a serious crime in their past ready to be returned to the outside world?
