The smooth effects and speedup of previous performances for the story of Jeff, just levelling off after the death of his wife, Adela, when he meets Penny- her sister- who looks too much like her. In the love which he transfers to Penny, Jeff returns to the Carolinian island which was Adola's legacy, confronts the hatred of Lynn Meredith whom Penny loves, the secrecy surrounding a child's death in the past, a murder in the present and the abortive attempts against his own life. The medium of suspense, the technique of tension given the full treatment.
