Two half-brothers fight for control of a Cosa Nostra family. The conflict is coming to a head as the Cosa Nostra Commission has scheduled a meeting in Chicago. A woman in love with one of the half-brothers is seized as leverage. The case is so important to the FBI that Assistant Director Arthur Ward joins Inspector Lewis Erskine and Special Agent Tom Colby as a bureau team of agents converges on O'Hare Airport. For the FBI team, the question is whether the Cosa Nostra members can be arrested without causing harm to the public.
