This glossy Lyon-set domestic drama marks the directorial debut of French singer and actress Mélanie Laurent. The film depicts the seemingly indestructible bond between a mother (Clémentine Célarié) and her two 20-something daughters, musician Lisa (Laurent) and her bibliophilic adopted sister, Marie (Marie Denarnaud). When Marie falls in love with Alex (Denis Menochet), Lisa and her mother go through some uncomfortable moments as they adjust to the idea that their beloved Marie no longer belongs exclusively to them.
