Michelle (Hélène Vincent) is a seemingly tranquil grandmother enjoying her retirement in a small village in Burgundy, France. Her existence would be idyllic, if only it were not blemished by her strained relationship with her adult daughter, Valérie (Ludivine Sagnier).

When Valérie drops off her son for a week with his grandmother, Michelle sees an opportunity to reconnect, but an unfortunate culinary mistake soon undercuts whatever trust remains. Now, with the help of her longtime friend Marie-Claude (Josiane Balasko), whose son (Pierre Lottin) has recently been released from prison, Michelle plots a path towards restoring the family life so long denied her.

Celebrated French director François Ozon cooks up a twisty thriller which balances familiar comforts with unexpected developments in a story where family ties prove to be the most dangerous ingredient of all.
