A young woman, Daniella, is sent to prison for crimes she does not know she committed. It seems her boyfriend Tony was involved in a drug delivery, but all the while innocent Daniella thinks he is carrying baking soda for his bakery. While in prison, Daniella endures repeated threats and beatings intended to force her to tell the whereabouts of the drugs. She has no information to give and so is beaten more. Hilda, whose father's life is in danger because of the same drug deal, goes into the prison undercover to try to help Daniella. Hilda is treated as poorly as the rest of the inmates making it even tougher for her to get the information she needs to save both Daniella and her own father. The inner walls of the prison show the rape, humiliation and degradation suffered by its inhabitants as they are supposedly being rehabilitated. Inmates turn against each other and to each other as each serves her time and faces her own fears.
