In the late 1940s backdrop of a small Cajun community during the Jim Crow Era. Jefferson, a young black man, is accused and convicted of a murder for perpetrating a shoot-out in a liquor store which left three men killed. Being the sole survivor of a crime that occurred unwittingly, Jefferson is sentenced to death. The story unfolds his search for justice as within his trial, Jefferson's attorney explains to the jury "What justice would there be to take his life? Justice, gentlemen? Why, I would as soon put a hog in the electric chair as this." Jefferson's godmother, Miss Emma Glenn, and Tante (Aunt) Lou, the aunt of local school teacher Grant Wiggins, ask Lou's nephew Wiggins to turn Jefferson from a "hog" to a "man." However, in order to accomplish this they must first get permission from Sheriff Sam Guidry. They successfully ask Sheriff Guidry's brother-in-law Henri Pichot, whose family Miss Emma served for years, for assistance. Wiggins, who left his hometown for tertiary education, has returned from university to teach locally. Whilst Wiggins takes the job in contemplation of whether to maintain his position or to completely move away from the place of his childhood, both Jefferson's godmother and his aunt successfully persuade him to go on a prison-visit and impart wisdom to Jefferson before his death. Over the course of the novel, Grant and Jefferson unexpectedly form a close friendship as the two men both come to comprehend the importance of resistance and defying conformity. As they understand compassion, human struggles and existential revelations through their newfound brotherhood, Grant also forms a bond with the white Deputy Paul Bonin. In early February, it is announced that Jefferson will be executed soon, on April 8. Around then, Reverend Ambrose becomes concerned that Grant, an agnostic, is not teaching Jefferson about God and thus begins to visit him regularly to reverse Grant's spiritual impartments. The conflict reaches a head when Grant buys Jefferson a radio, which the seniors in the black community, or "quarter," see as sinful. The novel ends with the anti-climax of Jefferson's death by execution and, much to Grant's surprise, a visit from Paul in which he tells Grant that "Jefferson was the strongest man in that crowded room".[2]
The book provides perspective on the status of African Americans in the South after World War II and before the Civil Rights Movement. It shows the Jim Crow American South through the eyes of a formally educated African American teacher who often feels helpless and alienated from his own country. In the novel, Grant is the only educated black man in the area and the only member of the black community who might be considered capable of becoming free of overt oppression. The character feels his life and career choices are severely limited due to racial prejudices, an example of this in the novel being his instinct to refer to white male authority figures as "Sir". In order to break away from his social conditions, Grant's yearning to escape this situation heightens over time throughout the story. Grant feels that he is cornered by myriad forces: his aunt's incessant desires, pressures to conform to a fundamentalist religion that he does not believe, the children's needs to fulfil his role as a teacher, and the community's craving for proper leadership.[3]
The title of this novel refers to Grant's attempts to teach Jefferson a lesson.[7] In order for Grant to be able to show Jefferson how to 'become a man,' he must understand the meaning himself before imparting his learning to another person. In the novel, the butterfly acts as a symbol towards the end as proof that both of these men have succeeded in their goals to be spiritually transcended.
At this point Grant realizes that Jefferson truly did learn a 'lesson before dying.' When he says "It is finally over," he is not only referring to Jefferson's life, but states it as a double entendre that also acknowledges his cowardly nature before enlightenment is "finally over." The character has fully taken a stand for what he believes in. This insures that he, too, has benefited from this entire experience. Jefferson's life was sacrificed in order for the white people in the community to gain a better understanding of the value of the black members in all societies.[9]
