In 1955, a year after the birth of the National Liberation Front (FLN), Mahmoud was expelled from Algeria by the colonial authorities who feared his revolutionary speeches. At the age of 27, he arrived in the Algerian slum of Nanterre. Roughly questioned by FLN activists, in disagreement with the Algerian Nationalist Movement (MNA) who wanted to recognize theirs, he was then accepted as the local hairdresser and shoemaker. Subsequently, he became a driver during anti-MNA expeditions. Accepting increasingly dangerous missions, he is imprisoned by the French police and once again undergoes interrogations and special treatment by the police which will definitively undermine his sanity. One day, he no longer recognized his companions, and when joy broke out among the FLN militants, at the announcement of the signing of the Evian Accords, Mahmoud remained alone, frozen in an attitude of refusal, walled in his madness. Algeria has just won its independence.
