“Expose of the $8,000,000,000 gambling syndicate and its hoodlum empire!”

A telephone repairman in Los Angeles uses his knowledge of electronics to help a bookie set up a betting operation. After the bookie is murdered, the greedy technician takes over his business. He ruthlessly climbs his way to the top of the local crime syndicate, but then gangsters from a big East Coast mob show up wanting a piece of his action.
