The story revolves around a G8 meeting, held at a luxury hotel on the German coast, where the world’s most powerful economists are gathered to enact important provisions that will deeply influence the world economy. One of the guests is a mysterious Italian monk (Servillo), invited by Daniel Rochè (Auteuil), the director of the International Monetary Fund. He wants the monk to receive his confession, that night, in secret. But the next morning, Rochè is found dead.
As the investigation begins, it becomes clear that there were several suspects: a group of business leaders who had been lobbying against the proposed changes, as well as some members of the religious community who were unhappy with the economic policies being implemented. The murder was carried out by a ruthless killer who knew exactly how to get what he wanted.
The investigation leads to the discovery of a shocking truth: the murderer was none other than the very same monk who had been invited to the meeting. It turns out that the monk had been planning his own revenge for years, and had even orchestrated the death of Rochè in order to silence him once and for all. The monk had been working behind the scenes to sabotage the meeting and its proceedings, using his wealth and influence to manipulate the discussions and decisions made by the G8 representatives.
In the end, the monk is caught and sentenced to prison, but not before he has left a trail of destruction in his wake. The world economy is shaken to its core, and the international community is left wondering how such a powerful figure could have gone undetected for so long.
