The first film, Case.1 Tsumi to Batsu (Crime and Punishment), focuses on enforcer Nobuchika Ginoza and inspector Mika Shimotsuki. The team finds a traumatised woman and it is quickly apparent that a drug has altered her state of mind, Akane Tsunemori's team is directed to return her to a special experimental prison - the place where the woman worked as a therapist. Akane dispatches fellow inspector Shimotsuki along with two enforcers, Ginoza and Kunizuka, to investigate the prison while she and the rest of the team investigate the case in Tokyo. Through a new combination of drugs, therapy, and work, the prison has produced a different kind of society where latent criminal prisoners act in harmony with one another - keeping their criminal coefficients under 90 in most cases and carry out work valuable to society at large. Mika sees the woman as a criminal worthy of being killed but she and Ginoza realize that the woman used herself as bait to seek protection for a small child. Mika and Ginoza discover the warden is exploiting the prisoners to harvest nuclear waste that was buried beneath the prison, causing the prisoners to die of radiation. Mika records the warden's confession of her actions and reveals it to the prisoners. Mika then kills the warden, but the prisoners riot. Mika and Ginoza hunt down the rest of the complicit staff then begin working to protect the prisoners. They later find out the Sybil System knew of the warden's motive since the prison is located above the former dumping ground of the System's nuclear waste.
