L'ispettore Coliandro

Jelena, a young woman of Slavic origin, steals Coliandro's pistol while he is trying to arrest her for theft. Unable to let his fellow officers or superiors know what has happened to his weapon, Coliandro sets off on yet another personal investigation. In his search for the pistol, he uncovers an alliance between the merciless "Balkans Mafia" and the Neapolitan Camorra, as well as a racket involving the recycling of toxic waste.

A minor murder case would go unnoticed, were it not for the escorts, or high-class call girls, involved. Plus the fact that the investigation is being sandbagged from on high. Though Coliandro is told to work on other matters, he naturally begins a counter-investigation of his own. With the help of Simona, also an escort, he uncovers a complex plot that incriminates deviant portions of the secret service and strongholds of economic and political power.

A group of armed robbers takes the customers and personnel of a bank hostage, little knowing that Inspector Coliandro is using the bank's bathroom, or that there are three even more desperate criminals - armed with real weapons and not toy ones like the robbers – already in the bank, ready to do whatever it takes to retrieve important documents that could send them to prison. Coliandro, once again leaving his superiors speechless, foils both plots, saving the hostages in the bargain.

A band of gipsies robs the wrong house. Realizing as much, their chief Vlad tries to take the loot back. But, shortly after, he and a gipsy girl are killed. Another girl, who Coliandro once let go after catching her stealing, survives the attack and runs to the Inspector for help. Working alongside Elena, a young social worker specialized in gipsy affairs, as well as his fellow officer "Gambero", Coliandro uncovers a dangerous criminal band.
