Gregory Peck is the ambassador to the United States whose wife has a stillborn child. Without her knowledge, he substitutes another baby as theirs. A few years go by, and then grisly deaths begin to happen. The child's nanny hangs herself and a priest is speared to death in a freak accident. It turns out the child is the son of Satan and can only be killed with the seven daggers of Meggado.—Humberto Amador
