Nightcap

In a Swiss household built on chocolate money, Mika (Isabelle Huppert) runs the family firm and shares a house with her husband André (Jacques Dutronc), a celebrated pianist, and his teenage son Guillaume. Jeanne (Anna Mouglalis) turns up at their door after learning she was nearly switched with Guillaume at birth. Claude Chabrol sets Jeanne beside Mika and André at the same table, and the courtesy between the three of them starts to feel strained.
