Sam Seed, an insane mass murderer, is scheduled for execution at the hands of Warden Wright. After three attempts to electrocute, complete with boiling blood that steeps from his eyes, Seed is still alive. The executioner, Wright and the doctor collectively agree, that the breathing Seed be pronounced dead. He is bound and buried alive. After biting and clawing his way to the surface, Seed, the blood soaked, enraged madman, is now bent on vengeance.
