A lonely widower living in the Italian quarter of the city, whose only solace since the death of his wife is his little child, is reluctantly a member of a secret society existent among his countrymen. The active members of this society have observed with envy the success of another Italian and feel that they should share the proceeds of his industry without working for it, so to this end send the wealthy man a demand for $5,000, ostensibly to defray the expenses of their society. The rich man is defiant and consequently the society decides upon his annihilation, electing the widower to do the deed. He at first rebels against the move, but has little choice, for it is a case of the marked man or himself. Hence, off he goes on the terrible errand. In the meantime, the widower's child wanders off and is thrown down by an automobile and, though not injured, is carried into the doomed house just as the father places and lights a bomb beneath it. You may imagine the man's position when, as he is leaving the place, he sees his own child through the window of the room just above the terrible instrument of destruction.
