A Japanese investigator and a Detroit cop team up to track down a stolen prototype turbocharger.

This is the story loosely based on Cleveland disc jockey Alan Freed, who introduced rock'n'roll to teenage American radio audiences in the 1950s. Freed was a source of great controversy: criticized by conservatives for corrupting youth with the "devil's music"; hated by racists for promoting African American music for white consumption; persecuted by law enforcement officials and finally brought down by the "payola" scandals.

Financial wizard "Doc" Fletcher is sent by crime boss Joe Fiore to buy a bank in Switzerland in order to more easily launder their profits. When he arrives, Fletcher finds that the bank, acquired by his associate Prince di Siracusa, consists of some shabby offices above a restaurant. To make up for this, the Prince suggests that Fletcher invests in a silver mine owned by Shireen and Agha Firdausi. This solves one problem, but the mine also attracts the attention of some of the most powerful people in the silver business. Fletcher must pull out all his wheeler-dealing skills in order to keep hold of everything he's worked for, in the process romancing a banker's discontented wife.
