A revolutionary militant is murdered during the repression of May 1945. At first, his son gets confused for a long time and speculates on the actual circumstances of the murder (that still remain shady for some). He eventually becomes attached to the same ideal his father died for. The identity of the murderer is revealed in the beginning of the National Liberation movement of November 1954. Now the whole people is fighting the entire colonial system and not only an individual. Ahmed LALLEM
