Betty is a French film written and directed by Claude Chabrol. Stephane Audran plays Laure, a middle-aged widow who rescues Betty (Marie Trintignant), a disoriented young woman she meets at her favorite bar. Relishing her role as a victim, Betty tells her new friend about the collapse of her marriage and the loss of her children. But as the film proceeds, we realize that Betty is a predator who abuses people's trust, patience, and good will. Claude Chabrol has skillfully adapted this novel by Georges Simenon and made it into a riveting psychological study of betrayal.
