When the "strange stories about parenting rules" came to the world as an unexplainable catastrophe, countries fell into the horror of "wrong parenting will trigger death". The country established the "Cradle" center to respond. Chief psychologist Fang Yue, who has the dangerous ability to empathize with the residual emotions of the deceased, formed an alternative partner with forensic doctor Qin Zheng. They discovered that the only way to quell all the weird rumors and save the world was not to use force, but to use the precise cooperation of psychology and criminal investigation to "dissect" the family tragedy behind each twisted rule, and truly understand the cries of the children who had been ignored by the world. The ultimate truth is that the source of all this is just a genius child who wants to be seen, and his last cry to the world.
