An immersion in the world of the investigation services of the police and the gendarmerie. From the filing of complaints to arrests, the work of the investigators is detailed: fingerprints, first leads and first suspects, DNA analysis and wiretapping, spinning and work indicators. Braking, breach of trust, sequestration or burglary, various cases, often delicate, are brought to light.
