Five years after a student opened fire at an exclusive private high school, killing several students and a beloved teacher, the survivors gather for the first time. Sitting in the classroom where the attack reached its horrifying climax, the group shares the scars each bears, and discusses what — if anything — can be done to curb the escalation of gun violence in America. The students engage in a debate that takes them from solitary anger to communal grief, and learn that true healing begins with listening.
