Dead Ringer (1964) Edith (Bette Davis) attends her twin sister Margaret's husband's funeral. Her twin sister is financially well-off from her deceased husband's fortunes, but she's a vile person, while Edith is a struggling bar owner who's three months behind on rent. In a spontaneous moment, she shoots Margaret in the head and assumes her identity and the vast fortune which comes along with it. But she isn't able to fool everybody as Margaret's lover Tony immediately figures out that this woman isn't Margaret, it's Edith. He knows what she did and he's blackmailing her. Edith has nowhere to turn to. She can't turn to the police because she'll be forced to tell the truth and will be charged with murder, which at the time, carried the death penalty in California.
