Filmed over the course of nearly three years, the filmmakers behind Newtown use unique access and never-before-heard testimonies to tell a story of the aftermath of the deadliest mass shooting of school children in American history on December 14, 2012. Newtown documents a traumatized community fractured by grief and driven toward a sense of purpose.

Take a moment to watch the Newtown trailer, and watch on April 3 when it airs on PBS at 9 p.m. ET/PT, 8 p.m.
