1950年春,苏州市孤儿院一名意大利儿童于光天化日之下神秘消失!与此同时,上海市公安局外事警官正为一名美国教授延缓离开中国之事而大伤脑筋。谁也没有料到,这两起发生在两地、看似风马牛不相及的事件竟有着密切的关联。透过这起发生在半个世纪前的洋教授拐骗儿童案,我们看到真相的背后藏着人所不知的秘密交易。 In the spring of 1950, an Italian child in the Suzhou Orphanage mysteriously disappeared in broad daylight! Meanwhile, the Shanghai police station foreign affairs police officer is struggling with the delay of a U.S. professor in leaving China. No one had expected that these two incidents occurred in both places and there was a close correlation between the seemingly irrelevant events. Through this case of abduction of a child by a foreign professor that took place half a century ago, we saw behind the truth a secret transaction unknown to anyone.
