It is 1919.

On the desolate battlefields of northern France, the cannons of the First World War fell silent. Special forces now face a dangerous task: searching for the dead for mass burials.

Captain Mackenzie, who himself survived the war, still cannot bring himself to return home. First he must see to it that the bodies of his fallen comrades are found and laid to rest. However, his mission is turned upside down when his men make a gruesome discovery in the ruins of a German fortification.

Among the many missing soldiers is the fiancé of Amy Vanneck, who refuses to accept that his body may never be found. She sets out for France, determined to find out what happened to the man she loved.

Soon there is no dispute that Captain Mackenzie has discovered a war crime of inhuman cruelty. A dark truth begins to seep to the surface, and Mackenzie and Amy are drawn into the search for a psychopath for whom the atrocities in Two Storm Wood are not the end, but only the beginning.
