To his chagrin, young Marcel Pagnol and his family move back to their home in Marseilles, France, far from their pastoral holiday cottage in the hills. Determined, Marcel makes the long voyage back to the cottage on foot and lands himself in trouble. One day Marcel's father discovers a shortcut to the cottage, but it requires trespassing. Despite their trepidations, Marcel and his family begin using the secret trail to reach their cottage.

The works of Marcel Pagnol are a veritable monument of French cultural heritage. Based on previously unseen archive material, film extracts, novels, plays, interviews and letters, the film pays tribute to the major author and popular filmmaker, who made his life a work and his work a life's project.

This is the story of a wealthy bourgeois who marries his only child, a daughter, to a penniless nobleman because he hopes to use his son-in-law to get a title. The son-in-law is a lazy, affected stereotype; but M. Poirier is also a stereotype, of the obnoxious big businessman. The poor daughter, who falls in love with her husband, lets him walk all over her.
