Henri, his wife Apolline, brother-in-law Maxence, Jean and Paul are waiting for cozy evenings with board games and good food - a typical ski holiday. But on the first day Henri announces that he knows about the affair between Apolline and Jean.

After a feminist is found murdered in her own home, a police detective investigates the crime with the help of several determined women.

Apostrophes was a live, weekly, literary, prime-time, talk show on French television created and hosted by Bernard Pivot. It ran for fifteen years (724 episodes) from January 10, 1975, to June 22, 1990, and was one of the most watched shows on French television (around 6 million regular viewers). It was broadcast on Friday nights on the channel France 2 (which was called "Antenne 2" from 1975 to 1992). The hourlong show was devoted to books, authors and literature. The format varied between one-on-one interviews with a single author and open discussions between four or five authors.
