Polisse follows the daily grind for the cops of the Police Department's Juvenile Protection Unit. They are tasked with taking in child molesters, busting underage pickpockets, and dealing with relationship issues at lunch. They also interrogate abusive parents, take statements from children, confront teen sexuality, enjoy solidarity with colleagues, and laugh uncontrollably at unexpected moments.
These cops must balance their private lives with the harsh reality they face every day. Fred, the group's hypersensitive wild card, struggles with the scrutiny of Melissa, a photographer documenting the unit for the Ministry of the Interior.
