District Court Judge Alicja Mazur is renowned for her strictness towards criminals. She is a successful woman with a flourishing career and happy family life. Unexpectedly, she is accused of a murder she did not commit and sentenced to 15 years in prison. She must survive in the prison among the women she has previously sentenced. Battling the brutal reality of prison life, she simultaneously strives to prove her innocence and ensure the safety of her daughter, Hanka.

Judge Alicja Mazur did everything to escape from hell. After confronting Paweł Witkowski, she returns to prison. Unmasking her husband assures her of her acquittal. Despite Serafin's pressure, Hanka decides to admit to shooting her stepfather and accept the consequences. Will Alicja stay in prison to save her daughter? In the prison, there are staff changes. Hepner becomes the new penitentiary director, demoting 'Penis' to a mere guard. The new director quickly gains the favor of the prisoners. Only Alicja Mazur suspects there is more to it.

The echoes of the riot continue, and penitentiary director Hepner teaches the prisoners a hard lesson in humility. Bans, restrictions, and mandatory runs in the courtyard become the daily routine. Campina, Shibie, and Francy, designated by Alicja as witnesses of the auction of women on the darknet, are particularly affected. Hepner knows their testimonies could mean his downfall. Meanwhile, in the prison's mother and child unit, Kosa enjoys motherhood. Unfortunately, bruises appear on Miki's body. Kosa is suspected of child abuse.
