西蒙老师的一位年轻女同事西尔维·迪福接受校长的建议,想邀请西蒙夫妇做一次讲座,这次讲座的内容很特别,是作为二战劫难的幸存者来亲身讲述那段历史,可他们会接受吗?他们又有着怎样不为人知的过去呢? Sylvie Defoe, a young female colleague from Simon’s teacher, accepted the principal’s advice and would like to invite Simon and his wife to give a lecture. The lecture is very special, as a survivor of the World War II catastrophe to personally tell about that history. Will they accept it and what do they know about the unknown?
