A brutal gang of thugs kidnapped Ilan Halimi, a 23-year-old French Jew, because they believed that all Jews are wealthy. For 24 days in 2006, they tortured him, demanded an impossible ransom and spewed anti-Semitic invective. Ilan’s mother, Ruth Halimi (played by Zabou Breitman), tried but failed to convince the French police the crime was anti-Semitic. Alexandre Arcady’s film is heart-stopping. Menemsha Films.
