A young felon was sent to prison to serve his sentence, but it dropped a huge emotional bomb in the heart of the female correctional officer. She has always been idealistic and kind to prisoners. She applied for a transfer to the felony detention area, gradually getting close to her prey, winning his trust, and trying to arrange for him to meet his mother. Was it her maternal instinct that made her want to save this wild wolf, or was it that her dark past that had been hidden for many years was aroused and she couldn't stop? After all, prison makes people crazy, no! Madness and prison are just symptoms of the madness of discipline. The truth has no place under the distorted power. In the end, are ethical suspense, grievances and hatred all medicine for existential reflection? Before vomiting, there may be too much to pay back.
