Please answer the following question: Generate a question about the following movie plot: Jeremy is an emigre from Manchester who owns a small New York City cafe. The cafe becomes a haven for Elizabeth, a young woman, as Jeremy tells her that he saw her boyfriend cheating on her. Devastated, she stays in his cafe the entire night, eating a blueberry pie he made, and also telling stories about each other. Jeremy, having an eidetic memory, explains her the bowl of keys he is keeping, knowing the story of every person who left the key in his cafe and keeping it in the bowl in case someone comes back for them. Elizabeth leaves her key of her apartment and leaves Jeremy's cafe. Elizabeth, now calling herself Lizzie, eventually drifts to Memphis, Tennessee, where she takes two jobs, waitress by day and barmaid by night, in order to earn enough money to finance the purchase of a car. She regularly sends postcards to Jeremy, taking a liking to him, without revealing where she lives or works and, although he tries to locate her by calling all the restaurants in the area, he fails to find her. Later on, he decides to send out postcards to any restaurants she may be to try to find her. One of Lizzie's regulars at both jobs is local police officer Arnie Copeland, an alcoholic who cannot accept the fact his wife Sue Lynne has left him and is flaunting her freedom by openly socializing with a younger man named Randy. He confesses to Lizzie his many attempts at achieving sobriety have ended in failure, taking many AA meetings but failing. One night off duty in the bar where Lizzie works, he drunkenly threatens Sue Lynne with his gun if she leaves. Later on, Arnie drives drunk and dies after crashing into a pole. Lizzie comforts Sue Lynne at the crash site, before leaving town, and is given the money towards Arnie's tab at the bar, revealing to Lizzie that she made a mistake and that she misses him. The place where he died is also the place where they met, suggesting that he may have committed suicide. Heading west, Elizabeth now calling herself Beth gets another waitress job at a casino in a small town...
