The novel depicts that during the period of the Franco-Prussian War of 1970, when a French carriage was about to leave the enemy-occupied areas, a Prussian military officer detained it and forced a prostitute nicknamed Boule de Suif in the carriage to sleep with him. Boule de Suif rejected him out of patriotism and however, the other passengers with social status thought of their own interests and forced her to sacrifice herself for them. Then Boule de Suif compromised finally. But when the carriage sets out the next morning, those passengers changed into other faces, they isolated her and disdained talking with her. She felt that she was submerged in the contempt of those bad people, for they sacrificed her and then abandoned her like she was a piece of dirty trash.
