She gets confirmation of what she has suspected for some time: Her husband is involved in a long term relationship with a young woman who is the age of their daughter. What she doesn't understand is that Kurt doesn't want to merely divorce her, he wants her dead. He is willing to go to extraordinary lengths to make sure that Susan is out of his way permanently. Susan has to draw on strengths and amazing creativity she was unaware she possessed, to prevent Kurt's success. Only one question remains: Who will succeed in this struggle between life and death?
