In July 2023, the Nanxiao River in Xiaguan County, which had been dry for nearly two decades, was flooded due to a once-in-a-century heavy rain.

Wei Dong, the criminal police captain, investigated the matter as a member of the task force and accidentally got involved in a major case from twenty years ago.
