In Chicago, a crime syndicate tries to take over a labor union by killing its whistle blower treasurer and framing the honest union boss for the murder.

An honest union official named Blane is framed for the murder of another union official. Thus off the hook, the crime syndicate responsible for the crime is free to continue its activities. However, State's Attorney Jim Fremont begins to suspect that Blane has been set up. Fremont launches a new investigation.—Jim Beaver <[email protected]>
