The institution is run by a ruthless warden, Edna, who implements severe discipline, aided by her cruel and sadistic henchwoman, Charlie. Upon arrival, Jenny quickly discovers the oppressive and brutal conditions, with regular physical punishments and psychological torment. Her fellow inmates are mostly hardened delinquents or vulnerable girls like herself, all enduring Edna's stringent rules and Charlie's relentless intimidation tactics.

Jenny befriends Lisa, a sensitive inmate who has managed to maintain some sense of hope amid the brutality. Together, they endure the daily grind, navigating the political dynamics among the inmates and trying to avoid confrontations with the domineering Charlie. As tensions rise within the institution, Jenny and Lisa begin fostering ideas of escape and justice, hoping to find a way out of the nightmarish environment. Their bond strengthens as they face growing challenges, uniting them in their struggle against their oppressors while trying to keep their spirits alive in the perilous setting of the facility.
