This begins with a television interview given by real-life prison reformer Richard McGee who reacts to a well documented spate of prison riots by informing the audience that they, too, must bear their share of responsibility for the conditions endured by the inmates. We are then taken to Block 11 where it does prove remarkably easy - especially given the prevailing tensions across the system - to nobble a guard, take his three colleagues hostage and then within a few hours take control of their entire prison. It's "Dunn" (Neville Brand) who came up with their plan, and escape isn't his intention. He wants both the prison governor (Emile Meyer) and the state one (Thomas Browne Henry) to agree to a series of demands that will ensure a more humane form of incarceration in future. What now ensues is a delicately played game of chicken. The prisoners reckon they don't have much to lose by killing one of the hostages if they don't get what they want. The authorities are terrified that acquiescing might just be a taper to light fires in institutions all across the country. Don Siegel delivers quite a poignant drama as the inmates begin to factionalise whilst the powers that be struggle to resist a more direct intervention and Brand, Meyer and Robert Osterloh's "Colonel" help create a story that offers food for thought. We have no idea why these men are in prison, which means we must make our evaluations as to the modern-day version of torture and solitary confinement imposed to keep discipline or to break spirits, or both, blindly? Yes, it is a bit predictable, but still worth eighty minutes.
