在18世纪的法国,一个女孩(苏珊娜·西蒙宁)被迫违背自己的意愿宣誓成为一名修女。三位母亲的上级(莫尼夫人,圣克里斯汀修女和谢尔夫人)对待她的方式完全不同,从母性关怀,虐待狂迫害,到女同性恋的欲望。苏珊娜的美德给每个人带来灾难,这是对启蒙哲学家丹尼斯·狄德罗对宗教滥用的猛烈抨击的忠实改编。In eighteenth-century France a girl (Suzanne Simonin) is forced against her will to take vows as a nun. Three mothers superior (Madame de Moni, Sister Sainte-Christine, and Madame de Chelles) treat her in radically different ways, ranging from maternal concern, to sadistic persecution, to lesbian desire. Suzanne's virtue brings disaster to everyone in this faithful adaptation of a bitter attack on religious abuses by the Enlightenment philosopher Denis Diderot.
