[1] On New Year's Eve in 1997, Shane Batesman organizes a big party to which he invites all his friends and classmates, but around 200 guests show up.
In the house across the street, the McIntoshes are also celebrating with some friends, but they are disturbed by the noise and Bob, the homeowner, decides to go looking for Shane to ask him to turn the volume down.
Just when Katy thinks about throwing in the towel, one of the boys sends an anonymous email which includes details that shed new light on the investigations.
Ryan decides to confess, and admits that he was the one who hit Bob repeatedly and kicked him, while his friends only shoved him.
Ryan was sentenced to five years in prison and, once released, he and Katy start speaking at high schools to warn young people about the dangers of excessive alcohol consumption.
