[4] The film follows Paulin Broquet, the chief of police, as he struggles to recapture the escaped crime lord Zigomar and his ally, La Rosaria.

The cast consists of Alexandre C. Arquillière as Zigomar, André Liabel as Paulin Broquet, and Josette Andriot as La Rosaria.

Shortly after, Paulin Broquet is lured into a trap and brought before Zigomar, who offers him a generous £50,000 if he leaves him to pursue his criminal activities freely.

Meanwhile, Zigomar and La Rosaria have launched their plan, stealing a lockbox of money won by a lottery with the help of a circus elephant.

The banker, however, already had a plan in case of a situation such as this, and shows Broquet that his safe is trapped, and when Zigomar and his gang try to open it, it triggers.
