He has been silent for three years in prison, but he actually hides the secret of the case in his heart. The prison has a strict hierarchy, and a delicate balance is maintained between guards and prisoners. A rare thunderstorm night became a turning point. When Jiang Lin touched the iron railing of the corridor, he was struck by lightning and gained the ability to read minds within a 10-meter range - he could hear the true unspoken thoughts of others, and the more intense the other person's emotions, the clearer his voice.
At the same time, young prison guard Zhang Jianjun was transferred to the prison area. He was once an elite member of the criminal police team, but was demoted due to a mistake in an unsolved case. He cherished the obsession of "digging out fish that slipped through the prison", but was ostracized by his veteran colleagues because of his upright style. The fate of the two people intertwined due to a bizarre theft case, starting a special cooperation between "prisoners and police detectives".
