Chaos reigns at the Tianhai Wharf during the Republican era—smuggling syndicates collude with Japanese forces, using demonic ghost-raising sorcery to murder witnesses and secretly transport weapons and poison gas.

Forced to take charge of a string of serial murders, he fights tooth and nail to protect Tianhai Wharf—and every citizen of the city.
