Nancy and George have been married for seven years, but their marriage is crumbling. George is always busy with work, leaving Nancy to raise their six-year-old daughter Sophie alone. On Sophie's birthday, Nancy and Sophie get into a car accident. Nancy desperately calls George for help, but he dismisses her, believing she is lying to get his attention—because he is busy comforting his first love, Vivian, and her son Peter, who were in the same accident.
Sophie is rushed to the hospital and needs a blood transfusion. George is the only match, but Vivian manipulates him into believing Nancy is lying. When George gives Sophie's blood to Peter instead, Sophie dies. Nancy is devastated, but no one—not even George—believes her. Vivian, determined to keep George, intercepts Nancy's message about the funeral and sends George a photo of himself kissing her, making him miss his own daughter's funeral.
At the funeral, the truth is finally exposed. Vivian stole Sophie's blood, bribed the nanny, and deleted George's messages. George finally realizes the magnitude of his mistakes, but it is too late. Sophie is gone, and Nancy refuses to forgive him. In the end, George is left alone at Sophie's grave, consumed by guilt, while Nancy walks away to rebuild her life without him.
