Yabo (Louis Garrel) and Marianne (Laetitia Casta) met on the university campus. The two fell in love at first sight and soon came together and moved under the same roof and began to live together. One day, Marianne told Yabo that she was pregnant. Before Yabo was happy, Marianne broke the shocking news that the child in her belly was not Yabo's, but Yabo's best friend Paul. Angry and shocked, Yabo chose to leave Marianne, and not long after, Marianne married Paul. Since then, these people have never contacted each other again, but the harm brought to Yabo by this relationship has accompanied him throughout his life. Nine years passed in a flash, and one day, Yabo unexpectedly received the news of Paul's death.
