Marseille, July 1905. Nearly a teenager, Marcel Pagnol embarks in his last summer vacation before high school and returns, at last, to his beloved hills in Provence. What begins as a summer of boyhood adventures becomes one of the first loves, and unearthed secrets.

Before being extradited to Africa to stand trial, a notorious Belgian criminal is entrusted to the Marseilles police department for less than 24 hours. But the wily crook convinces bumbling policeman Emilien he's a lowly Belgian embassy employee who got railroaded by the brilliant master criminal.
