Fabio Leone and Paolo Pecora are two police officers of Rome which, together with the careless Neapolitan Ciro Marmotta, are fired from the barracks to have scuppered the plan to capture a secret agent. Fortunately the three friends manage to enlist in a guardhouse more specialized, which involves the VIPs protection in Italy and foreign countries, on a visit to Rome. But the three friends, who now also joined Romolo: the scullion of the bodyguards' association, always combine a lot of troubles.
