In Shanghai in 1932, unknown secrets were hidden in the bungalows in the French Concession, and the oil lamps in the shanty towns burned with an unyielding glimmer. Shen Zhiwei, an architect who returned from studying abroad, returned to this treacherous city with the obsession of restoring her family's old house. However, she was accidentally involved in a conspiracy that spanned the three circles of military, government and business - the drawings of the old house in her hand contained a code that could shake up the current situation.
However, Lu Jingchen, the inspector of the concession patrol house who was ordered to investigate the case, was as cold and cold as the rocks on the Huangpu River. However, in his dealings with Shen Zhiwei, he gradually got a glimpse of her tenacity and edge under her gentle appearance. One is a "foreign lady" who carries the family's past, and the other is a "lonely detective" who walks on the edge of black and white. When the hatred of the country and the family is intertwined with the love of his children, they test and redeem each other in the torrent of the times, but they do not know that fate has already written a footnote for them destined to be entangled. The jazz music in the foreign house is intertwined with the sirens on the street. Under the prosperity of the ten-mile foreign market, there is an undercurrent of crisis, as well as the love and hate that they cannot let go.
