Kieleck is more than an overzealous officer in a high-security prison. He is the true ruler behind these walls. Not only prisoners but also unwanted colleagues fall victim to his intrigues. To maintain his order, he will stop at nothing. However, Kieleck has a secret. During a letter inspection, he falls in love with Anabelle, the wife of a prisoner. She becomes his ray of hope in this world of steel and concrete. When the prisoner one day wants to divorce Anabelle, Kieleck's mind threatens to unravel. In his attempt to prevent the separation, his dark side emerges—the side of a cruel, sadistic psychopath. He is the law.
