Mitch is a rich and powerful man, however, and soon, Slim begins to discover a dark side to him. One day she discovers that he has been cheating on her. Though Mitch apologizes to her, his infidelity doesn't stop. Slim discovers this when she smells his mistress' perfume on him one day when he comes home from work. As Slim berates him for cheating on her, Mitch slaps her and then punches her in the face. Mitch believes that his money and power will give him anything, and he threatens to kill her, saying that he refuses to live without her. The police cannot help, because the best they can do is jail him for a short period, and meanwhile she would risk losing her daughter to state family protection programs. Slim would also be at the risk of Mitch killing her while out on bail.
Mitch stops all her credit cards and freezes her accounts. Slim and Gracie then flee to a motel, but Mitch finds them. They escape on a public bus, and move to Seattle, where she meets with her former boyfriend, Joe, who still has feelings for her. Meanwhile Mitch turns to Robbie, his contact in the Los Angeles Police, the same man who had verbally abused Slim at the diner. It emerges that Mitch and Robbie had scammed several women using the "verbal abuse" trick, and Mitch had several mistresses. Mitch locates Joe's residence and sends three men there under the guise of FBI agents to search for Slim and Gracie, but are unsuccessful.
Slim and Gracie flee again, with the help of her estranged father Jupiter and her former boss/father figure Phil, but are tracked down in northern Michigan, where they are confronted by Mitch face-to-face this time. Slim manages to break free and later sends Gracie to stay for a month with Ginny, her friend from the diner. Meanwhile, with Jupiter's help, Slim trains in Krav Maga, preparing herself emotionally and physically for self-defense. She prepares herself for a visit to Mitch's new beach house to hopefully get him to leave her alone.
She breaks into Mitch's new house and removes all potential weapons, and familiarises herself with the layout of the place and planting letters of evidence. When Mitch returns home, she attacks him and overwhelms him, but cannot bring herself to kill him. She calls Ginny and asks what she should do, but Mitch recovers and knocks her unconscious. Ginny becomes hysterical on the phone and Mitch hangs up. Slim recovers and manages to turn the tables on Mitch. He falls two floors and dies after landing on a table on his back.
The police arrive and tell Slim that Ginny had called the police to save her. She then tells the officer that Mitch is inside, but no longer armed or dangerous. The officer tells Slim that it looks like she's "one of the lucky ones". She goes to the airport and reunites with Gracie. In the final scene, she is seen holding hands with her old flame, Joe.
