Nicola Persico is a retired ex-General of the Guardia di Finanza whose life is marked by a solid routine. What no one knows is that underneath his clothes hides Federico Sinacori, a long-time con man who has been the subject of investigations all over the world. However, the man decides to return to action when the tenants of the building where he lives are scammed by a financial company that expropriates their apartments.

Nicola leads a gang of ordinary people - a surveyor, a bartender, a taxi driver, a terrible old lady, a former opera singer and a newlywed couple - who, led by him, become a gang of swindlers ready to do anything to get revenge on the financial company that tried to bring them to their knees.
