Madame Cuno en haar zoon Louis worden lastiggevallen door twee van hun dorpsgenoten die er op blijven aandringen hun huis te verkopen. Eén van de buren wordt door een mislukte grap per ongeluk gedood door Louis en de andere buurman wordt ervan verdacht zijn vrouw vermoord te hebben. Inspecteur Lavardin is vastbesloten de zaak tot op de bodem uit te zoeken en schuwt daarbij geen enkel middel. En de waarheid is behoorlijk schokkend.
