Professional killer Holland (Charles Bronson) is forced out of retirement to break a Central American government's political torture ring when one of his friends, a Latin American journalist, is killed. The murderer, Dr. Clement Molloch (Joseph Maher), is the master sadist behind the political torture of innocent victims. Posing as a journalist, Holland lures Molloch out of his fortresss-like headquarters by using his murdered friend's wife (Theresa Saldana) and daughter as bait. When Holland kidnaps Molloch's sister (Antoinette Bower), the doctor is led on a wild chase that takes him to an abandoned opal mime where he finally comes face-to-face with Holland. Their long-awaited confrontation soon comes to a shattering conclusion.
