To prove her worthiness to inherit the multinational conglomerate Sterling Global, Blair Sterling accepts a perilous corporate assignment: reform Blackwood, a brutal maximum-security women's penitentiary. Disturbed by rumors that guards murder inmates for sport, Blair enters the compound undercover as convict zero-zero-seven to gather irrefutable proof.
Inside the concrete fortress, the sadistic warden and his depraved son subject Blair to ruthless beatings and solitary confinement without suspecting her identity. Unbroken, Blair organizes an underground revolt among mistreated prisoners, seizing control of the facility before appearing at the executive boardroom to personally dismiss the corrupt wardens.
