As the First World War rages, a lone assassin navigates sprawling fields of death by secreting himself within the soiled mazes of the ravaged frontlines. The young Native American soldier, Anong, conflicted by loyalties and his place in the world, must cross lands seeded in local superstitions and ancient folklore. When he saves a young boy from a pack of predatory locals, Anong, and the child soon find themselves facing something far more frightening than the horrors of war.

Russell Stander, returning to the same ancient quarry where his mother met her own grisly end decades earlier, helps recover a newly revealed find. Alongside a team of handpicked archeologists, Stander puzzles over what has been unearthed. Desperate to shed light on the scattered and varied pieces of the evolving mystery. But what emerges - voraciously hungry, disturbingly malformed, and shockingly violent - keeps Stander and team cloaked in darkness.

Can any light be found within the trench?
