Sue Klebold

As the disaster of yet another school shooting hits, some parents are faced with a brutal fact: their child was the one pulling the trigger. Jeff Williams is the father of Andy, who in 2001, at the age of 15, shot and killed two classmates and wounded 13 other students. Andy, 25 at the time of filming, is now serving life in prison. Clarence Elliot’s son Nicholas shot and killed his teacher and wounded another in 1988. He too is serving life in prison. Sue Klebold’s son Dylan was one of the two teenagers behind the Columbine High School massacre in 1999, one of the deadliest school shootings in history. Dylan ended the shooting by committing suicide. Through the three parents' deeply personal stories and raw, honest testimony, the film explores multiple themes that emerge from terrible tragedies - guilt, failure, responsibility, sorrow, friendship and love.

Sue Klebold attempts to reconcile how the son she affectionately referred to as "Sunshine Boy" became a school shooter. "If love could have stopped Columbine," she says, "Columbine would never have happened."
