One of the most powerful Mafia Godfathers has broken the organisation's code of silence: omerta. The confession of Tommasso Buscetta gives a unique insight into Mafia operations in Italy and the United States. His evidence has already led to over 100 arrests. Martin Young reports on the organisation which included the world's biggest drugs racket and on the secret operations of the FBI which show how a billion dollars worth of narcotics were smuggled into America. In Italy, Buscetta reveals the links between organised crime and respectable politicians. On both sides of the Atlantic it is being hailed as a historic breakthrough in the battle against the Mafia - the so-called Men of Honour.
