Lock Up [Includes Digital Copy] [4K Ultra HD Blu-ray/Blu-ray]

A model prisoner approaching the end of his sentence is abruptly transferred to a high-security prison run by a cruel and sadistic warden. The warden, responding to several incidents at another prison, makes an example of the new inmate, but when the prisoner starts fighting back, it's hard to tell whether the warden is captor or captive.
