Spiral Season 6 begins with the shocking discovery of a dismembered human torso in a pile of garbage in the 20th arrondissement in Paris. Police Captain Laure Berthaud returns from maternity leave to reunite with her colleagues Gilou and Tintin, and together they tackle the complex investigation. The trail leads them to a northern suburb where Laure's mentor Commissioner Herville was transferred, and where the team will face off against institutional corruption and organized crime in a neighborhood devastated by poverty and delinquency. Meanwhile, a high-profile criminal trial tempts lawyer Joséphine Karlsson, and Judge Roban faces a rapidly escalating health crisis. This new season pushes every character to their limit and forces them all to question long-standing affiliations and beliefs.
