After surviving the horrors of the Great War, Paul Shenstone works as a police detective in 1920s Toronto, rooting out petty criminals and rumrunners. The unusual murder of a prominent industrialist gives him the biggest case of his career and a not entirely welcome opportunity to make his name on the force. The waters are muddied when the investigation starts uncovering connections between the deceased Digby Watt and soldiers Shenstone knew in Flanders. What will Shenstone's choice be if he has to arrest one of his own comrades? He has promised Watt's attractive and independent daughter that he will bring the perpetrator to justice, but bonds forged in war are not easily broken. In the end, what does justice require, restitution or punishment?
