Clyde Shelton's family is brutally murdered. The ones responsible are caught. However, because of improper procedure, the D.A., Nick Rice only has circumstantial evidence.

Ten years later, the one who was convicted is being executed but something goes wrong; his execution goes awry and he suffers. They learn that someone tampered with the machine. And the other one is found dead, killed in a gruesome manner. Rice suspects Shelton, so he has him picked up. At first, Shelton agrees to a plea agreement with Rice but changes his mind. It appears that Shelton is not done, it appears he blames the whole system and is declaring war on it going after everyone involved with his family's case. So Rice has to stop him but Shelton is way ahead of him.—rcs0411@yahoo.com
