Joan Crawford gives a terrific performance in this chiller from pioneer horror movie producer William Castle.
Crawford plays Lucy Harbin, a woman who goes berserk when she finds her husband in bed with another woman. With her three-year-old daughter accidentally witnessing the grisly act, Lucy axes the couple to death then spends twenty years in a mental institution for the double murder.
After she is released, she moves in with her brother, his wife and her own daughter, now twenty-three. Her nightmare is over...or is it?
