Adapted from a novel by Georges Simenon, Betty stars Marie Trintignant in the title role. A drunken wastrel, Betty is adopted after a fashion by an older female alcoholic named Laure, played by director Claude Chabrol's wife at the time, Stéphane Audran. Fascinated by Betty's hard-luck tales, Laure endeavors to protect the younger woman from the ravages of a cruel world. Unfortunately, she turns a blind eye to Betty's larcenous streak, which manifests itself at the worst possible moments. This tale of a irredeemable ne'er-do-well is fleshed out by a flashback-flashforward technique that some observers found confusing and distracting.
