Rage

In this grim actioner, the directorial debut of distinguished actor George C. Scott, a widowed rancher and his young son go to Wyoming for a camping trip and end up accidentally sprayed by an experimental, deadly nerve gas. They are sleeping when the fateful substance is dropped. The next morning the father finds that many sheep are dead and that his son is unconscious. His nose bleeds heavily. The father rushes the boy to the hospital and the doctor suggests that the father also undergo a few tests. Unfortunately, the army gets wind of them and replaces the doctor with one of their own; he has been given orders to keep father and son apart; so the new physician heavily sedates the man and whisks the dying boy away. When the father awakens, the doctor assures him that the child is well, but its a lie; the boy is dead. Meanwhile, the ranchers are all puzzled by the death of their stock and frustrated because authorities remain tight-lipped to prevent panic and to keep the father around to see how the gas will affect him and how he will eventually die. The father continues to wander about the hospital under heavy guard, but they cannot prevent him from seeing the disposal of his dead son's clothing. He manages to overpower his guards and force a doctor to tell him the truth. The bereaved father, realizing he only has a few hours left to live, goes berserk with grief and rage. He then busts out to spend his final moments getting bloody revenge. Tragedy ensues.
