Winter 1935, Shanghai French Concession. In order to find out the truth about her father being framed for smuggling opium, Su Wanqing was forced to become the "canary" of the East China Governor-General Gu Tingchen. He gave her fine clothes and food, and also gave her prison and shackles. She circled in his palm, weaving a web under his nose. Everyone said that Miss Su was the young marshal's favorite bird, but she was the only one who knew that what was tied to this golden chain were two hearts that plotted against each other. When the truth emerged, she realized that in this game that started with a transaction, it was no longer clear who was the hunter and who was the prey.
