DETECTIVES | M6 | Zone Interdite

There are almost a thousand of them in France. When a police investigation goes awry, to find a missing relative, or to obtain damages in the event of a conflictual separation… private detectives are often the last resort when it comes to redressing private injustices. But they’re not the only ones. More and more companies are calling on their services to gather evidence against unscrupulous employees.

Stakeouts, shadowing, hidden cameras, disguises… Private investigators stop at nothing to gather evidence and carry out their investigations. For several months, we’ll be following the daily lives of four of them. They all gave us their permission to be filmed with their faces uncovered. Through their investigations, each more incredible than the last, we’ll discover the keys and tricks of this fascinating and little-known profession.
