Film in three parts: Raymond Depardon films L'ambuscade d'Aouzou, in Chad, where Gilles Caron, Michel Honorin, Robert Pledge and a group of rebels are attacked by Chadian auxiliary troops in 1970. The other two parts (1975-76) include an interview with Françoise Claustre, a captive of the Frolinat fighters led by Hissène Habré and Goukouni Wedey, and the attack on the Faya palm grove. Raymond Depardon's interview for this short documentary moved public opinion, and Paris relented, paying the ransom demanded by Hissène Habré, amounting to ten million francs. Françoise Claustre's story served as the basis for Raymond Depardon's film La Captive du désert, starring Sandrine Bonnaire.
