Chimène, a beautiful young creature, has everything to make heads spin. Her nickname, Pim-Pim Tché, the not very flattering "my dirty little bitch," suits her perfectly. A virtuoso when it comes to the emotional scam, the 17-year-old has already had to repeat a year of school, but is determined to move up a class this year in order to acquire a school grant. But before reaching this paradise, she has to juggle highly unappealing jobs to ensure that she can eat breakfast, help out her parents who are always flat broke, and trick her maths teacher who also happens to be her paternal uncle.
