La poliziotta della squadra del buon costume (1979)

Agent Gianna D'Amico wants to advance her career and tries every way she can to get assigned to the vice squad. She has to make a name for herself and earn Commissioner Nardecchia's respect, but that is no easy matter for a policewoman—especially since D'Amico is so scatterbrained that she arrests her own immediate superior, Commissioner Scappavia. At last, she gets the right opportunity to prove her abilities: when she comes across a prostitution and human-trafficking ring operating behind the front of a nightclub, she chooses to take action without telling anyone. To carry out the operation, she uses her beauty to get hired at the club as a singer. When they learn she is in danger, her boyfriend, Agent Arturo, comes to her rescue, along with her two colleagues, Commissioner Scappavia and the hapless Agent Tarallo. The two colleagues disguise themselves as women to get into the club, but when two customers approach them, their disguises are exposed. A brawl breaks out, and the boss flees, pursued by Gianna and Tarallo, with Scappavia and Arturo joining them. After a long chase, all the criminals are arrested. Commissioner Scappavia is then appointed head of the vice squad, and Gianna manages to join the unit.
