This polar inspired by real events, takes place in the judiciary or justice background. It stages four characters in their daily life. Each day, Mathilde Armani, a young instruction judge, is sharing her office with Nacer Bessa, her Clerk. On the Police side, Marie Belmont, a very sportive cop, is investigating with Alexandra Samowicz her colleague. Those heroes are getting into those dramatic situations with impertinence. This new type of Police series is written in a very innovative narration style : each case is dealt throughout a chronological reconstitution of the facts. The narrative style uses ellipses, off voices, sixframe… At last, the turning point of the investigation is the instruction, also because judges are most of the time some women. Damage is in the heart of our daily life society.
