From the archives of the criminal police in London the unfaithful policeman Larsen steals a microfilm documenting the crimes committed by a sector of “cosa nostra” headed by “John il maltese” and hands it over to the boss of the rival gang Astruan the Tunisian. The two gangs , detective Teddy and his friend Jane, journalist of the times, hunt for the microfilm. After many attempts the gang of joe in tunisi exterminates the other and destroys the microfilm. Obviously the good microfilm will remain in the hands of Teddy who will take it back to the London archive.
