At the end of the 19th century, an orphan comes to live with her aunt and uncle in Normandy. The girl is taken in not only out of philanthropy, but because she has a large inheritance that is held in trust. The child grows up and is attracted to her cousin, an underachieving airhead, whom she later helps out of financial difficulties as a young woman. After her aunt's death, she takes over the household and helps the family financially. The planned marriage to her cousin fails when a rival appears. This is the story of a selfless woman who, despite her disappointments and low lives, refuses to let them take the joy out of life.

In 1879, the Minister of Fine Arts Edmond Turquet commissioned Auguste Rodin to create a colossal sculpture for the future Musée des Arts Décoratifs. Referring to the bronze door executed in the 15th century by Lorenzo Ghiberti for the Baptistery of Florence, and considered by Michelangelo to be "the door to paradise", Rodin spent over three decades imagining every creature and every detail of La porte de l'enfer. The ten-panel work, inspired by Dante's The Divine Comedy, was never entirely finished. After the artist's death in 1917, several sculptures were extracted from the monumental matrix, including The Thinker and The Kiss.
