What happened to Bette Davis after What Ever Happened to Baby Jane? Her career was reborn. Warner Bros. Encored it with another vehicle filled with Baby Jane-like bite and menace: Dead Ringer, stylishly directed by the lady's Now, Voyager costar Paul Henreid.

Davis plays estranged identical twins. Unmarried Edith has no money, no future. Widow Margaret has fabulous wealth - all because of marriage to the man she stole from Edith years ago. Out of long-festering revenge, Edith kills Margaret and takes her place. But new friends and surroundings, a snoopy cop (Karl Malden) who was Edith's beau and the arrival of Margaret's secret lover (Peter Lawford) may expose her masquerade.
