It is the story of twenty days of childhood, in the mid-fifties. The young boy enters the age of reason. Dictatorial parents appear fragile and fickle. The authoritarian teacher becomes an automaton. Too often missing grandparents change into loving humans.Now vast and hostile nature turns into a delicate and pleasant picture.The first car changed Sundays into great Sundays.After a long journey to his father's Brittany, the young boy met all his unknown family, undiscovered landscapes and the sea.
