The film tells the story of the scandal of Banco Ambrosiano, mainly related to the figure of Roberto Calvi.

The Clearstream scandal exploded as a case full of intricate affairs involving the financial world, the Vatican, the Masonic Lodge P2, the Italian Secret Service, the Secret Intelligence Service, the Italian politics, the Mafia and the Banda della Magliana.

The film ends with the death of Calvi under the Blackfriars Bridge, in London, openly supporting the murder-hypothesis.

According to the director Giuseppe Ferrara, he started the project in 1986, soon after The Moro Affair, and wanted Gian Maria Volonté in the main role of Roberto Calvi.
