Calling on expert testimony and dramatic re-enactments, the documentary series Solved! Forensic Police Files (Police scientifique) takes us into the heart of police investigations in which science plays a preponderant role. In 30 episodes covering as many crime files, the series shows us how police work and new technologies are indissociable. While DNA, ballistics, and forensic biology have become part of the everyday vocabulary of police work, the latest scientific methods yield surprising results and lead to the resolution of crimes that formerly went unpunished.
