Film Synopsis

Dr Jean Marcelin, a spry fifty-year-old, leads a contented bourgeois life with his wife Lucie, seemingly unaware that she is an incorrigible coquette who is having an affair with a friend of the family, Fernand Worms.  The doctor's decision to engage an attractive young woman named Juliette Lecourtois as his secretary is ill-received by his wife.  She had hoped that he might have hired her lover for the post.  One evening, the entire Worms family is invited to dinner at the Marcelins.  The master of the house, usually a stickler for punctuality, keeps his guests waiting.  Someone comes to the door holding the doctor's jacket.  In the pocket is a recently made will which will raise more than a few eyebrows when it is read.  It seems Dr Marcelin was fully aware of his wife's infidelity and consequently has chosen to leave two-thirds of his estate to Madame Worms, his former mistress, and another woman who bore him an illegitimate daughter...
