She meets a weathered old man who she learns is her grandfather (Brahim Ben Salah), who warmly welcomes her and tells her that her mother works far away in a luxury resort, but that she returns home each Friday. Rallia also meets her aunt Nedjma (Baya Belal) who is mentally challenged and ostracized by the community. Waiting for her mother to return, Rallia tries to participate in the family’s daily life and encounters the hardships of the desert.
