Cousin, Cousine

Their unfaithful spouses have provided them with license to fool around, but there's much more at play than romantic revenge in the pairing of Ludovic (Victor Lanoux) and Marthe (Marie-Christine Barrault). After meeting at a family gathering and realizing that they're related by marriage, the attractive young duo forges a sophisticated relationship, one that increasingly looks like it might turn sexual. Perhaps predictably, some onlookers are less than enthusiastic about the evolving kinship.
