La Rupture
Helene is a good mother with a checkered past as a stripper and  barmaid.  She divorces her ne'er-do-well husband and her in-laws blame her for causing  her husband's addiction and set out to remove their grandchild from Helene's custody.   Thwarted by the courts, they hire a seedy penniless operative, Paul, to destroy her  reputation.  He moves into her rooming house and begins to insinuate himself into her  life, hatching darker and more convoluted plots to implicate Helene.  A harrowing thriller  from France's master of suspense, LA RUPTURE ranks among Chabrol's finest works.
