The TVI Take

A French police procedural following the overlapping worlds of police, prosecutors, lawyers, and judges in Paris. The most detailed portrayal of the French legal system in drama, educational about inquisitorial vs adversarial legal processes.

Exceptional craft across eight seasons. Better than comparable American procedurals in institutional complexity.
