Synopsis translated from fr.wikipedia.org/wiki/Sophie_et_le_Crime
"In Paris, the young Sophie makes her journalistic debut at Tel Quel, a small echo weekly, when her neighbor, Louise Richter, is murdered. The main suspect is her husband Franck who disappeared immediately after the tragedy. One evening, this one surprised Sophie in his building, claiming his innocence. Convinced, Sophie then makes her investigation to exonerate him."
