A stern pharmacist finds his life disrupted by his long-lost, intellectually challenged half-sister in this endearing comedy. In the wake of her mother's death, simple-minded Nénette (Josiane Balasko) was searching for her estranged father when she instead found her dour half-brother Paul (Michel Blanc). Paul is a man who savors order in his life, and the whirlwind of chaos that follows Nénette's unannounced arrival sends his anxiety levels spiking. But as rigid Paul is about to find out, sometimes all it takes is a little love to show us exactly what we've been missing in life.
