It is the future, and humans are divided into two groups: the thinkers, who make plans (but don't know how anything works), and the workers, who achieve goals (but don't have the vision). Completely separate, neither group is complete, but together they make a whole. One man from the "thinkers" dares visit the underground where the workers toil, and is astonished by what he sees...
It's the picture that has the whole town shivering!
A cabal of American industrialists, all fifth-columnists intent on sabotaging the war effort, are methodically murdered by the malevolent Monsieur Colomb. It is only until detective Dick Martin is assigned to the case that everyone's true motives and identities are revealed.
A sadistic count tortures and murders his unfaithful wife and her lover, then removes their hearts from their bodies. Years later, the count remarries and the new wife experiences nightmares and hauntings. The ghosts of the slain return to exact their bloody revenge, until their hearts are destroyed.
