Synopsis by Robert Firsching
Chinese filmmakers Li Sibing and Liu Guoquan co-directed this spy film set in the city of Binghai. Acting on an outside tip that an espionage ring is planning to kidnap the famous Professor Ouyang Yujie (Zhang Jie) and smuggle him out of the country, the Public Security Bureau sends Detective Zhou Xiang (Guo Bichuan) to guard the renowned doctor and determine which of his close associates is one of the criminals. It turns out that Ouyang's doctor, Liu Lu (Guo Yuxiang), is the culprit, but is torn in two directions because she has fallen in love with the professor in the interim and commits suicide before providing information. When the criminals strike, Zhou and his fellow agents are caught off-guard, and must use every ounce of their skill and training to protect Ouyang. Li Lin and Li Xiaoli co-star.
