In the autumn of 1937, on the eve of the fall of Shanghai, the Wang Mansion in Huacheng, the "No. 1 Fragrance in Asia", fell into unprecedented confusion and fear. Mrs. Wang and her husband Wang Dayou had a premonition that Huacheng would become hell, and they wanted to send their children out of the city. However, Wang Lilun, the young master of the Wang family, and his three sisters did not want to leave the city for various reasons. For a while, there was a lot of fog and danger. Wang Lilun was unaware of the dangers around him and was full of fantasies. He wanted to make a love movie. In order to cope with the arranged marriage between Mrs. Wang and Wang Dayou, he forced Huang Xixi, a female worker in the Royal Fragrance House, to be his contracted girlfriend. Later, the two pretended to be true and loved each other from hatred. He found out that the idol star Wang Qier was Wang Dayou's "lover" and Mrs. Wang called him a "fox spirit". He was in great pain. After a serious illness, he cheered up under the inspiration of Xixi. Unexpectedly, the director invited Wang Qier to play the leading role. After all kinds of friction, the misunderstanding was resolved. It turned out that Wang Qier was a member of the underground organization of the Communist Party of China, and it was also the party's task to approach Wang Lilun and enter Wang Mansion. Mrs. Wang is the heir of Yuxiangfang. She has a great talent for incense making. She went to Japan for further studies and was involved in the Japanese conspiracy. Under the hypnosis of Dr. Huo, her terrible memories gradually awakened and became the "scar" in her heart. She fought with Xu Xiaoxiang, the owner of Xujixiangfang, and sent people to go undercover; she and her husband Wang Dayou did not trust each other. She was exhausted from defending her ancestral business and suppressing foreign forces. Later, Mrs. Wang and Xu Xiaoxiang came to their senses and jointly accused the Japanese army of crimes. Wang Qier, Wang Lilun, Xixi and others were searched by the Japanese army when they were distributing leaflets at the city hall dance. Wang Qier was taken away and sacrificed by the Japanese army to protect Xixi. Wang Lilun and Xixi continued to mature after experiencing various changes. Wang Lilun understood the hypocrisy of the Japanese army. He destroyed the pro-Japanese film film and used ventriloquism to help Mrs. Wang lure Mayor Ma, Xicun and others to kill them, destroying the Japanese conspiracy and joining the anti-Japanese camp.
