In Tianjin in 1937, the city was intertwined with Western-style buildings and alleys. Overtly, it was the sound of the concession, but secretly it had been turned into a mess by all forces.
Zhou Hu, a ruthless character from the Green Gang, was quietly killed at a night stall, which made the already tense Jinmen even more upset. People from the "Northern Gang" became the number one suspect.
On the other side, a theater in the French Concession was singing "Farewell My Concubine". Su Wan is a mainstay. She just won the first place in the "Tinmen Famous Actress" competition and is known as "Sister Su". Carrying the blood feud of her whole family being wiped out, she circled among the rich and powerful in Tianjin in order to uncover the enemy who destroyed her family ten years ago. At this time, Shen Yanshan, the helmsman of the Haihe Chamber of Commerce, was sitting in a box in the theater. Her fate took another turn.
The two stumbled amidst gunfire and drama, and finally tied together. Su Wan, whose heart and eyes were full of Shen Yanshan, could only say "Thank you for your love" to Lu Shaozhou, the young master of the Lu family who was chasing after her to throw gold and silver. When the relationship between the three people became entangled, Shen Yanshan's identity as a secret agent of the "Northern Gang" was also revealed. All forces focused on their weaknesses, and the Green Gang was the most ruthless. In order to get rid of Shen Yanshan, they dug up the old case of Su Wan's parents, exposed the Shen family's "inaction" back then, and wanted to use her hand to kill him.
The foreign cars in Tianjin were still running, and the Huqin in the theater was not stopping, but the two of them were forced step by step into the dead end of the alley in the concession, wearing costumes and suits when they first met. Perhaps in those days, the more people wanted to hold on tightly, the easier it was for them to be trapped in the troubled times and become a pair of moths, burning up their whole lives and never flying out of the city's fog.
