Susan Hapgood, a shy, quiet girl, cannot believe how lucky she is that rich, attractive Martin Summerslee wants to marry her. After a whirlwind courtship, Susan and Martin are married and head towards Martin's estate in Maine. But even before they get there Susan has apprehensions. She feels a shadow over her--that of Martin's first wife, Irene, killed in a plane accident. Irene had been a beautiful, accomplished woman, and Susan feels she is always being compared to the first Mrs. Summerslee. Soon Susan becomes aware of an evil presence threatening her happiness, sanity, and even her life itself. As jealousy and terror begin to control her life, Susan becomes more and more helpless, until it seems as if nothing can save her.
