Set in a time of uneasy peace and opportunistic alliances in ancient China, The Spring and Autumn Murders tell the story of three friends, Hai, Lei and Zian. With a friendship forged in military training and battle, they are sent from their home kingdom of Zhou to a village in the northern area of Jin to help patrol the border against barbarians from the surrounding mountains under the direction of Lord Nianzu, the local magistrate. It appears to be a normal assignment, but the three friends soon discover that nothing about this new detail is routine.
While Hai and Lei make their first nightly patrols in the area, Zian is surprised in camp by a panic-stricken, bloody Hua, fiancé of their employer’s son. Zian sets out to find his comrades, and returns with them, only to find Hua missing, and mercenary soldiers riding into their camp intent on finding the murderers who have terrorized the village below, killing the only son of Lord Nianzu.
Now it’s a race to find Hua and the truth between the three friends, the military that is chasing them, the grief-stricken Lord Nianzu, and the real killer, who each have their own motives for finding the girl. The trails lead each group through quite a number of surprises, uneasy alliances, the ever present spirit world, and more bloodshed to find the truth that sometimes even the quietest of villages hide the darkest secret imaginable.
