Dolores

Suspected of killing Vera Donovan, her wealthy employer, Dolores Claiborne tells police the story of her life, harkening back to her disintegrating marriage and the suspicious death of her violent husband, Joe St. George, thirty years earlier. Dolores also tells of Vera's physical and mental decline and of her loyalty to an employer who has become emotionally demanding in recent years.
