It was aboard the legendary and sturdy Peugeot 504 and Renault 12 that most North African families made the "route du bled," a ritual return to their homeland for summer vacations in Morocco or Algeria. The film chronicles a summer migration across the Mediterranean from the 1970s to the 1990s. The memory of these epic journeys punctuates the history of North Africans in France with bittersweet nostalgia, where travel stories blend industrial automotive heritage with personal memories.
