From the moment she glimpses at her idol on the stage door, Eve Harrington (Anne Baxter) moves relentlessly towards her goal: taking the reins of power from the great actress Margo Channing (Bette Davis). The cunning Eve maneuvers her way into Margo's Broadway role, becomes a sensation and even causes turmoil in the lives of Margo's director boyfriend (Gary Merrill), her playwright (Hugh Marlowe) and his wife (Celeste Holm). Only the cynical drama critic (Oscar winner George Sanders) sees through Eve, admiring her audacity and perfect pattern of deceit.
