A retired private eye living out his days at his late wife's rural French estate gets thrust back into action after the murder of six local nuns.

Amin, an aspiring screenwriter living in Paris, returns home for the summer, to a fishing village in the South of France. It is a time of reconnecting with his family and his childhood friends. Together with his cousin Tony and his best friend Ophélie, he spends his time between the Tunisian restaurant run by his parents, the local bars and the beaches frequented by girls on holiday. Enchanted by the many female characters who surround him, Amin remains in awe of these summer sirens while his dionysiac cousin throws himself into their carnal delights with euphoria. Armed with his camera and guided by the bright simmer light of the Mediterranean coast, Amin pursues his philosophical quest while gathering inspiration for his screenplays. When it comes to love, only Mektoub (‘destiny' in Arabic) can decide.
