Differences from the original version
The series is rather similar to the original Italian version. Most of the episodes are remakes of episodes from the Italian version, with the settings of the episodes relocated to France and characters given French names, though the second season featured a few episodes with original plot lines.

The head of the French RIS, Marc Venturi, shares the last name with the head of the Italian RIS, Riccardo Venturi, but aside from that, none of the other names are the same.
