In the winter of 1983, three-year-old Cen Xiaoman rushed into the county public security bureau with his army cap in his arms and shouted in a milky voice: "Dad, there is someone crying under the river embankment, and there is a pair of red shoes hidden in the car!"
Officer Pei Yanchuan rushed to the scene. The deserted ferry was empty, but there was half a child's shoe print left in the mud.
Xiaoman held his clothes and pointed all the way to the abandoned granary, helping him uncover the trafficking gang that had been absconding for many years.
From then on, Zaizai became Pei Yanchuan's most special assistant in solving crimes.
She can identify a crying child behind a wall and point out where the killer has hidden evidence.
Seeing that she was young, the evildoers coaxed her with candy and laughed in public. In the blink of an eye, she was brought to the witness stand.
But in the new case, the dark shadow that always follows Xiao Man actually calls out Pei Yanchuan's nickname after he has been missing for many years...
