Found in an alleyway, completely dazed, with no memory of who she is, or how she's gotten there, an obviously well-to-do young woman is taken to a nearby shelter. There she meets former cop Michael Coffey, when he rescues her and the nun running the shelter from an attack by an unknown assailant. After the attack, it's clear the shelter is not a safe place for her to stay while she waits for the veil of amnesia to lift. Pursuing an elusive memory she has of a motel, Coffey drives her to the location, only to discover a brutally murdered man in the room, and blood-splattered clothing that would certainly fit his companion. Is she a cold-blooded killer, or has someone set her up? Coffey is positive she's innocent, and determined to help her. But the truth which his investigation gradually reveals is so shocking that is will be almost impossible to prove. For the real criminal is someone she trusts implicitly - someone who has tampered not only with the truth but with this innocent victim's very mind!
