Description：Alice Lantin (Virginie Efira) is a 38-year-old single mother. She is beautiful and motivated, but in the eyes of her ex-husband, she is boring, so she devotes herself to the work of the magazine. Alice was qualified to be the next editor-in-chief, but her superiors and colleagues felt that her image was too old-fashioned and stereotyped, and she was helpless and frustrated. On a plane, she happened to meet Balthazar (Pierre Niney), a young and handsome guy who had just turned 20. When the two were together, they were seen by their colleagues and misunderstood that she was engaging in a fashionable sister-brother relationship, so their attitude towards her also changed. Alice felt that this accident was the key to her promotion, so she took the initiative to start a plan to seduce Balthazar. It was an unintentional meeting.
