在这部天方夜谭剧情片中,当乔治•图尔姆斯（Georges Turmes）在卢森堡市-贝唐堡的火车上第一次遇见雅米娜（Yamina）时， 她只是一个他要检验车票的乘客 。 当他又一次在同一辆火车上看到她时，她试图躲藏在洗手间，被严重殴打过，脸上满是血迹。乔治给予她帮助，她违心的接受了。 此举将搅乱了他们的生活。
Georges's life is turned upside-down when he meets Yamina and decides to help her. While she seems to be persecuted and living in hiding, Georges's reality is rooted in a daily routine without any surprises. Yamina's stories fascinate him: her happy childhood under the rhythm of a song, the massacres in the 1990s in the Great South, as well as her difficulties in Algeria and then in France. Georges spends more and more time with Yamina and is totally disorientated the day she disappears without a word. As his search for her unfolds, Georges realizes that he knows nothing about her and that every person he meets who knew Yamina seems to have a different version of the young woman's life. Convinced that he must go to Algiers to save her, Georges abandons everything and sets out on a journey without any concrete destination. His quest finally leads him to an oasis in the Sahara, a desert that spreads as widely as this love story between Bonnevoie and Tabelbala.
