In Shanghai in the 1930s, Xu Wenqiang, a patriotic student from Peking, was imprisoned because of the student movement. He was frustrated and went to Shanghai alone. When he first met Ding Li, a slum hawker, the two became sworn brothers in times of adversity and shared life and death together.
Wen Qiang relied on his classmate socialite Fang Yanyun to gain a foothold. By chance, he rescued Feng Chengcheng, the daughter of the French Concession gang tycoon Feng Jingyao. Cheng Cheng fell in love at first sight and pursued love persistently. Xu Wenqiang, whose heart was frozen, gradually fell in love. In desperation, the two brothers took refuge in Feng Jingyao. Wen Qiang became a celebrity in Feng Mansion with his resourcefulness and courage, and entered into an engagement with Cheng Cheng. But Wen Qiang gradually discovered that Feng Jingyao had colluded with the Japanese spy Yamaguchi Xiangzi, resold arms, and killed patriotic Jingwu Sect patriots. . .
