Denial (2016)

Every day our changing climate pushes us closer to an environmental catastrophe, but for most the problem is easy to ignore. David Hallquist, a Vermont utility executive, has made it his mission to take on one of the largest contributors of this global crisis-our electric grid. But when his son Derek tries to tell his father's story, the film is soon derailed by a staggering family secret, one that forces Derek and David to turn their attention toward a much more personal struggle, one that can no longer be ignored.
