One night, several prison inmates take guards prisoner to protest brutal conditions in their prison. They then make their demands known to prison warden Reynolds (Emile Meyer), a liberal-minded administrator who has complained for many years about the same conditions. James V. Dunn (Neville Brand), the prisoners' leader, meets the press outside the cell block and makes demands that they will no longer tolerate the brutal guards, substandard food, overcrowding, and barely livable conditions.
