Huddled in a cloakroom with his classmates and teacher, six-year-old Zach can hear shots ringing through the corridors of his school. A gunman has entered the building and, in a matter of minutes, will have taken 19 lives. In the aftermath of the shooting, the close knit community and its families are devastated. Everyone deals with the tragedy differently. Zach's father absents himself; his mother pursues a quest for justice - while Zach retreats into his super-secret hideout and loses himself in a world of books and drawing. Ultimately though, it is Zach who will show the adults in his life the way forward as, sometimes, only a child can.
