After the death of her husband, Christine realizes she has possibly wasted her life by marrying him instead of the man towards whom, in her youth, she had a stronger inclination. To overcome these dreary thoughts, she decides to find out about him and the other men who danced with her during a ball that was a turning point in her life, many years ago. She pays a visit to those forgotten acquaintances one after the other; Christine is not only surprised to see how they have fared, but also discovers the impact she had, unknowingly, on the feelings and the destiny of these persons.
