In a future one hundred years from now, in a world where the sun has become a distant memory and snow and ice are a permanent state, seven child prophets have been sent to bring the light back into a world where darkness now reigns. Aiding them in their quest are a small group of humans from different backgrounds and faiths along with the last of the archangels, led by a disgruntled Gabriel and steadfast Michael. It is now a race against time to unite these seven "trumpets" of God before the light leaves the world and those who reside within it forever.
