In old Shanghai, female lawyer Qin Sang was sorting out a drowning file from five years ago and found a sentence hidden in the yellowed file: "Sister, I'll wait for you below." This last word was like a key that fell into the water, bringing the dust-laden truth to the surface layer by layer - the death of Paramount singer Chen Baidie, which led to the dirty deal between the patrol room and the public prosecutor's bureau. Witnesses were hidden, evidence was erased, and everyone who sought the truth disappeared inexplicably. Qin Sang chased step by step along the unfinished road of his father, and uncovered not only a murder case, but also a dark web covering the French Concession. In the end, justice was not absent, just because someone insisted on turning on the light in the dark night. She leads the roots in the mud to the sun and lets her footsteps settle in spring.
