Aspiring young tennis player Jonas (Jonas Bloquet) gets terrible marks on his high school exams, so Pierre (Jonathan Zaccaï), a friend of Jonas' family who is in his 30s, offers to tutor him. However, it isn't long before the lessons go beyond academics to instruction in sex. While Jonas finds Pierre's seemingly open and liberated attitude refreshing at first, it is soon apparent that this older gentleman is actually manipulative and irresponsible, and the relationship deteriorates.
