Paulin Broquet, the great Parisian detective, has brought the notorious bandit, Zigomar, to justice. Determined not to let the law punish him, he had taken poison in the Hall of Justice. Then he was brought to a hospital where he lay motionless and was visited by hundreds of persons. Among the visitors was a slender woman, dressed in black, who secreted herself in the hospital, and, when all the others had gone, went to the bedside of Zigomar and administered an antidote for poisoning.

The next dastardly trick of Zigomar was to secure the safe which carried $50,000 belonging to the owner of the Grand African Circus, which he had won as a prize. He and La Rosario, disguised as servants, joined the circus and by the aid of a powerful elephant managed to get the safe to a manhole into which is was lowered to Zigomar and La Rosario.

After a time of suspended activities, Zigomar attempted to rob the biggest bank in Paris; but in this he was frustrated by the detective. Swearing vengeance he tried to wreck the train upon which the detective was traveling, but one of the detective's spies got wind of it and warned him.

A sensational detective story, founded on the romance of Leon Sazie. The noted criminal who terrorized all Europe is shown in these three Zigomar reels in a dramatic and intense struggle for supremacy with Paulin Broquet, the celebrated detective, who takes the two in the most varied and finest resorts.
