影片《危险方法》(A Dangerous Method)原名《谈疗法》(The Talking Cure)，根据英国编剧Christopher Hampton（《赎罪》）的同名舞台剧本改编。 　　萨宾娜·斯皮勒林（凯拉·奈特莉 Keira Knightley 饰），出身俄罗斯犹太家庭。1904年被送到苏黎世去治疗歇斯底里症，成为了精神病医生荣格（迈克尔·法斯宾德 Michael Fassbender 饰）精神分析患者中的一员。荣格发现她有受虐倾向，是一个性瘾患者，同时又有深深地自责心。而在诊治过程中，他们之间发生了秘密的、不论之爱。但荣格重视自己的声誉，想要隐藏这段感情，声称萨宾娜是一名臆想狂。而这种欺骗的行为也让荣格在理念上与恩师——精神分析学派创始人弗洛伊德（维果·莫特森 Viggo Mortensen 饰）分道扬镳。Suffering from hysteria, Sabina Spielrein is hospitalized under the care of Dr. Carl Jung who has begun using Dr. Sigmund Freud's talking cure with some of his patients. Spielrain's psychological problems are deeply rooted in her childhood and violent father. She is highly intelligent however and hopes to be a doctor, eventually becoming a psychiatrist in her own right. The married Jung and Spielrein eventually become lovers. Jung and Freud develop an almost father-son relationship with Freud seeing the young Jung as his likely successor as the standard-bearer of his beliefs. A deep rift develops between them when Jung diverges from Freud's belief that while psychoanalysis can reveal the cause of psychological problems it cannot cure the patient.
