This is a gritty, gut-wrenching doc about two unlikely friends – a convicted murderer and a young filmmaker. David McCallum has served 29 years of a life sentence and may never leave prison again. Despite a mountain of evidence that should exonerate him, or at least trigger a new trial, filmmaker Ray Klonsky and a pro-bono team are stymied by a justice system that has proven reluctant to exonerate the wrongly convicted. When news of a DNA match that fingers a new suspect emerges, the team thinks justice will finally be served. Instead, they realize that their fight has only just begun.
