Brahim Nad­hour, a Tunisian who has been living in France since he and his wife sep­a­rat­ed, returns to Tunis to bury his son, Marouane, who died in a motor­cy­cle acci­dent. He dis­cov­ers that the young man had been active in a rad­i­cal Islamist group and decides to find the rea­sons for his rad­i­cal­iza­tion and to iden­ti­fy the people who indoc­tri­nat­ed him. In the course of his inves­ti­ga­tion, he begins to doubt the cir­cum­stances of his son’s death.
Brahim’s mis­sion reveals a glimpse of Tunisian soci­ety today. In the neigh­bor­hood where he used to live, he meets many lib­er­al-minded people who are nonethe­less very care­ful when they answer his ques­tions, out of fear of per­se­cu­tion. His ex-wife, a sec­u­lar intel­lec­tu­al and esteemed author, lives in fear of attacks during public appear­ances. The film clev­er­ly plays with the form of the detec­tive story and was pro­duced with a high level of authen­tic­i­ty and many ama­teur actors, cre­at­ing a sim­i­lar feel­ing as the films by the Dar­d­enne broth­ers, who also co-pro­duced it.
