When Guillaume Valmont dies in a car accident, the only thing he leaves his wife Isabelle is his pharmacy. She never loved her older husband and she regards his death as a deliverance. At the funeral, she meets Judith, widow too, and she soon realises that her husband had been leading a double life. A short while later, the pharmacy is broken into, but nothing is stolen. Police Inspector Laforêt is put in charge of the case. Isabelle becomes suspicious when Judith offers to buy the pharmacy.
