In Mong Kok, Hong Kong in 1937, the smoke has not yet arrived but there is an undercurrent surging. Su Shangyin, the only daughter of a Shanghai textile family, was forced to seek refuge with distant relatives in Hong Kong due to a sudden change in her family and the death of her parents. From the rich lady of Xiafei Road to the dance hall singer of Mong Kok Flower Lane, she amazed the romantic world with her poetry and calligraphy, but in the end she could not escape the crushing times and the darkness of people's hearts. A passionate love affair with the prodigal Liu Xia Xiang, and a fateful entanglement with the social butterfly Ling Hua, eventually pushed her into the cold waters of Victoria Harbor. This is the story of how a person maintains poetry in despair, and it is also a fable of how a city breeds new life in chaos.
