In the seventeenth year of the Republic of China, the Yu family in the south of the Yangtze River was trapped. The daughter Yu Qinghuan escaped death and lived in Shanghai. She met Shen Mohan, the marshal of Songhu, and temporarily stayed in the Shen Mansion. As the two gradually fell in love, political rival Li Yunlong and adjutant Zhao Qiming colluded with Japanese consul Yoshio Yamamoto to frame Yu Qinghuan as a spy and alienate the two. Yu Qinghuan did not give up. He and his maid Cui'er discovered the rebellion plot and pretended to surrender to the enemy to send a message. After Shen Mohan learned the truth, he rescued her and jointly set up an ambush to defeat the rebels and the Japanese army. Yu Qinghuan even broke into the consulate to collect evidence and vindicate the Yu family. In the New Year of the following year, Shen Mohan married her with ten miles of red makeup, and the two worked together to protect Shanghai.
