It is 1905, and Chicago is an open town. The most accessible part of town is the Levee District. It is an area of the city that’s hard to tell the crooks from the cops. There are brothels, madams, opium dens, gambling joints and plenty of alcohol, but it all comes at a price in the Levee, and the two Ward Aldermen get their share of every vice’s dollar. With the hanging of serial killer, Simon Kluge, police Detective Patrick Moses is suddenly without a case. Before Moses can relax, he is approached by an aging retail mogul who asks him to investigate the mysterious shooting of his son.
As Moses gets deeper into both cases, he realizes that in the Levee there are a lot of people who don’t want the two cases solved, including the police and the Ward Aldermen.
