Marge d'erreur (2014)

Rebecca (Anny Duperey), a lawyer, realizes that the young man (Julien Crampon) whom she has exonerated after a brilliant defense could in fact be the culprit of the murder he is accused of, and that he may be planning another crime. Rebecca's personal inquiry leads her all the way to Belgium, where she crosses her ethical 'red line' when she meets Malice (Emilie de Preissac), a young police officer. An impulsive hot head, Malice leads her on a wild ride through Brussels.
