Revolt in the Big House stars Gene Evans as a prison "lifer" who rules the roost in his particular cell block. With the help of such loose cannons as prison psycho Timothy Carey, Evans engineers a jailbreak. As the cons and the cops sweat through a standoff, it becomes clear that Evans doesn't care how many of his fellow prisoners die so long as he busts out. Conscience-stricken inmate Robert Blake saves his cell mates from the consequences of Evans' recklessness. Revolt in the Big House is excessive violent at times, but never so much as to become "Revolting in the Big House."
