A kind of seawater desalination technology developed by a research team in China is coveted by international technological criminal organizations. Zhan Feng is the prospective son-in-law of Dai Xingguo, the mentor of the research team. In order to protect this technology and his future father-in-law and wife, he attracts rioters and is later attacked and loses his memory. Dai Xingguo’s favorite protégé Nie Lingfeng harbors resentment towards him. At a critical moment, he switches sides and reaches an agreement with the criminal gang. Nie Lingfeng keeps Zhan Feng in his luxurious villa and arranges for his niece Liu Shiyin to take good care of him. Taking advantage of Zhan Feng's amnesia, he rewrites his life resume to extract scientific research and technical data, and is ultimately caught.
