Warning: full spoilers, including the ending.
The film's protagonist is a fictionalized version of the real Antonio "Toni" Chichiarelli, and the historical record supplies the shape of the plot. Chichiarelli built a career as an art forger in the service of Roman gangs and fraudsters, and his talent for imitation eventually put him at the edge of the country's biggest political crime: he is linked to the forged communiqué issued after the 1978 kidnapping of former Prime Minister Aldo Moro, a false statement claiming Moro had been executed. That document sent the state's search efforts in the wrong direction at the most critical possible moment — the film's central demonstration that a piece of paper in the right handwriting can move a nation.
The second pillar is the 1984 Rome vault robbery, widely dubbed the "robbery of the century," in which Chichiarelli and two accomplices took roughly thirty-five billion lire — on the order of fifty million euros in today's money. The heist is the culmination of his double life: the same meticulousness he used on canvases applied to an operation against a security depot.
What makes the story a tragedy rather than a caper is that Chichiarelli was killed in Rome in 1984, not long after the robbery. The film's climax stages this end as an ambush — and here is where the adaptation departs most audibly from the record. Italian critics singled out the reversal of the ambush in the finale as the clearest instance of the film "sacrificing the truth," alongside a broader softening of who Toni actually was. Read after the fact, that choice reframes the whole picture: the retrospective meaning of Toni's life is that he was useful to people who could later dispose of him, and that the same anonymity which protected his forgeries left nobody obliged to account for his death.
The hidden design that becomes legible only at the end is the parallel between the three friends from Rieti. Toni counterfeits objects, don Vittorio operates inside an institution built on inherited authority, and Fabione believes in a political project — and all three are instruments of forces that outlast them. The film's final irony is structural: a movie about the greatest forger in Italy, which openly presents a novelized and prettified version of his life, quietly becomes the last fake in his catalogue.
