The plot of "Dancer in the Dark" takes a tragic turn when Selma's landlord, Bill, who she has confided in about her savings, steals her money. When Selma confronts him, a struggle ensues, and Bill, in a moment of despair, begs her to kill him. Selma, with her poor eyesight, accidentally shoots him and, at his insistence, ultimately beats him to death to retrieve her money. She is arrested and put on trial for murder. In court, Selma refuses to reveal the full truth of what happened, as she had promised Bill she would keep his financial troubles a secret. This, combined with her seemingly emotionless demeanor (a result of her internal escape into music), leads to her being convicted and sentenced to death.
In prison, Selma's friends, Kathy and Jeff, discover the truth and recover her money. They use it to hire a lawyer who believes he can get her a new trial. However, Selma refuses his help when she learns that his fee is the same amount as the money she has saved for her son's operation. She chooses to sacrifice her own life to ensure her son will be able to see. The film's devastating climax shows Selma being led to the gallows. She is terrified but begins to sing to herself to find courage. Just before she is hanged, Kathy rushes in to tell her that the operation was a success and that Gene will be able to see. Selma is hanged before she can finish her final song, and the film ends abruptly.
