Seven years ago, the Jade Seal Case erupted. Shen Mo, son of the capital's judicial commissioner, lost his family, was framed, and was exiled to the frontier.
Seven years later, he returned under a cloud of guilt and became the head of the Crime Bureau, the most unusual government office in the capital. He seemed carefree and unruly, but possessed a keen mind that noticed every detail.
Back in the imperial capital, he found not only that everything had changed, but also a string of bizarre, unsolved cases:
A ghost bride vanished into thin air inside her wedding sedan. One hundred thousand taels of silver went missing from the imperial treasury. Students at the Imperial Academy were poisoned one after another... Behind each case seemed to be an invisible hand, drawing him toward the tip of the iceberg that was the injustice from seven years ago.
Forced to work alongside him was Lin Qingxue, daughter of the Imperial Medical Director and the capital's foremost female coroner. Childhood sweethearts in the past, they were now bitter colleagues. His unexplained disappearance years ago had turned her love into resentment, leaving her cold as ice. They clashed at every turn on the job, yet when their lives were on the line, they had no choice but to trust each other with their backs.
Meanwhile, Zhao Wuya, commander of the Imperial City Guard, seemed to be both friend and foe. He had helped them several times, yet always appeared to be hiding another side of himself...
