L'ispettore Coliandro

Coliandro, a young, low-ranking police officer in Bologna, accidentally comes into contact with Nikita when she comes to see a colleague of him in another department. She wants to show him a suspect package that she has been given to deliver. Coliandro, seeing this as his big break in the force, offers to help her. The package contains a large sum of money in cash and a mysterious floppy disk that blocks the police computing system. When they try to deliver the package to the addressee, they find him dead in his office.

Chinese child vanishes, leaving behind a dragon key ring. Urged on by his sweet but insistent niece, Inspector Coliandro, theoretically on leave to look after the little girl, begins an investigation of his own within Bologna's Chinese community.

Inspector Trombetti returns fire during a police operation in a dark garage. When the lights come on, the body of a local gangster is found, but he was unarmed. Trombetti is suspended, and there are even rumours that he once worked for the gangster. Coliandro, convinced of his friend's innocence, clears Trombetti and discovers who the dishonest cop really is, all with the help of the gangster's sister, with whom he falls in love.

A Nigerian girl is killed. After a series of blunders, Coliandro is accused of being racist. He is taken off the case and assigned to escort Kiru, the victim's sister, from Nigeria. The two wind up having a passionate affair as Coliandro discovers that the victim was actually a maid killed by Kiru's sister, who was trying to get her hands on a large sum of money.

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.
