6x5 - Spiral

The body of a teenager is found in the rubble of a building. Warned by Herville, Laure is convinced that there is a link with the investigation into the murder of Mercier and is trying to recover this case. In parallel, she continues her investigations to shed light on the rape of Josephine. Furthermore, the ex-wife of Fromentin is worried because she is unable to reach their son. The panic spreads to the policeman because Ruben does not answer his multiple calls either.
