Overview: Chicago, July 1934. Anonymous phone calls have been tipping off Ness and his men to narcotics activities; they do a bunch of raids. On August 4, even though sales have fallen off, Frank Nitti is ordering 15 kilos of heroin*, the biggest single shipment ever. That night, one of Nitti's boys makes the trade: dough for the H. He gets into a car driven by another of Nitti's boys, Manny Kravitz.
