"BLACK MARKET CZAR!...Exchanging human lives for blood-soaked Profit!"

A private detective, soon to enlist in the army, is drawn into one final case when his police officer father is killed in the line of duty. Soon his prime suspect is murdered as well, and he finds himself framed for the crime. As more witnesses get murdered, he finds himself on the run from both the police and former Prohibition violators who seem to have found a new racket.
