LA RUPTURE is one of Claude Chabrol's most devastating critiques of the bourgeoisie and it's one of his finest films. It's about a working wife and mother fighting for custody of her small son after the boy's drug-addicted father has attacked them, only to find her husband's rich parents have hired a sleazy, corrupt investigator to destroy her reputation. The film isn't flawless; there are too many extraneous and eccentric characters but the main plot is beautifully handled, (it's based on a novel by Charlotte Armstrong), and Stephane Audran as the wife and Jean-Pierre Cassel as the investigator are both terrific. Of course, you may think Chabrol's decision to treat such a serious subject as domestic violence purely as a thriller a little tasteless but fundamentally this isn't really a film about domestic violence at all but an almost Dickensian study of evil; the bourgeoisie parents are distinctly rotten, the investigator even more so. If the film were more 'realistic' it might be unbearable; there's a scene of potential child sex abuse, and the child is mentally handicapped, that is almost too bizarre to be really disturbing and the film gets very bizarre towards the end. However, even with its convoluted plot it works superbly both as an outright thriller and as a scathing indictment of a highly amoral society.
