Based on the true story of a family tragedy that shook Tunisia in 2014: that of Olfa Hamrouni and her 4 daughters, two of whom were indoctrinated by ISIS, Kaouther Ben Hania’s “Olfa’s Daughters” brilliantly and insightfully dissects the indoctrination process through which Islamists brainwash the socially and psychologically fragile.

Thanks to an innovative narrative, halfway between documentary and fiction, this film, both sober and moving, has succeeded in establishing a captivating play of mirrors between the real-life characters of Olfa and her daughters and their fictional doubles on screen.
