Federal Agent Robert Mazur spent five years undercover as a money launderer to the international underworld, gaining access to the zenith of a criminal hierarchy safeguarded by a circle of dirty bankers and businessmen who quietly shape power across the globe. These men and women control multibillion-dollar drug-trafficking empires, running their organizations like public companies. Accountants, attorneys, and financial advisors, their roots run deep in their communities, and they are laundering billions of dollars a year, manipulating complex international finance systems to serve drug lords, corrupt politicians, tax cheats, and terrorists. In 1987, Mazur began infiltrating BCCI, bankers behind the Medell n cartel. He meticulously gathered evidence for years until, during a fake wedding, federal agents arrested over 40 high-ranking criminals, who were all found guilty and sent to prison. Never before told, this is the incredible, true story of how he did it.
