The New Girlfriend

Claire (Anaïs Demoustier), devastated by the death of her best friend, makes a promise to watch over her husband (Romain Duris) and newborn child. Battling through a fog of depression and a lack of responsiveness from her own husband, she reluctantly drags herself to the plush suburban home of her friend's widower only to make a startling discovery about the form his grief has taken.
