A teen gymnast is found molested and murdered. The prime suspects are her overbearing coach and the male team booster with whom she was having an affair. In the course of the investigation Benson and Stabler are surprised to learn the girl was not a teen at all, but a 19 year-old lying about her age. Though molestation is no longer an issue, the detectives press on to find the murderer. Eventually, the trail of evidence leads to the girl's envious teammate who was jealous that she was not first and foremost on the team.
