Kingdom Come (2013)

They sky has turned black and the world beneath it is cold and unforgiving. A soldier stumbles across some letters from a dead man and as he reads these letters, he's taken on a journey that leads him to rediscover himself and his own humanity. He changes for the better, for the good that remains in him, and the good that can be. The strength he finds to face evil head on leaves us with hope in humanity and the future of mankind.
