The short story "Hills Like White Elephants" by Ernest Hemingway does not have a plot in the traditional sense of the term. Two people, a man and a woman, wait at a railway station in the valley of the Ebro River in Spain. It is very hot. They sit outside in some shade and drink and talk.
However, beneath the seemingly placid surface of the story, there is clear emotional progression. The couple is on the way to Madrid so that the woman can have an operation. It is not specifically mentioned, but it is clear that she is going to have an abortion. Although the man continually repeats that he only wants her to go through with it if it is something that she also wants, he is obviously trying to coerce her into doing it. This is evidenced when he says that he doesn't want anyone but her. He doesn't want anyone else. In other words, a baby would affect their lifestyle so he doesn't want the intrusion. He keeps saying how simple and easy the procedure will be. In fact, in the 1920s when the story was written and published, abortion was illegal and was not simple at all. Medical complications were common for women who had abortions.
The woman is ambivalent about the procedure. She loves the man and wants things to be right with him, but at the same time she's not sure that the abortion will be so simple or that things will be the same for their relationship after it is over.
All of this is implied in the seemingly simple dialog until the woman has had enough of the man's persistence and pestering. She finally asserts herself strongly, first by saying, "Would you please please please please please please please stop talking?" and then by saying, "I'll scream." This is the climax, turning point, and most intense point of the story, when the woman expresses the tension that she has built up inside. Afterwards, she smiles at the woman serving them and tells the man that she feels fine, but for a brief moment she has let her real feelings emerge.
